Flutter based Client causes instant freezing and white screen (Windows 10 x64, Intel NUC with i5-4250U, Intel HD Graphics 5000)

[axbmcuser]

Bug Description

When starting a client version which is based on Flutter, Windows instantly becomes completely unresponsive/unusable.

How to Reproduce

• Start flutter based client on Windows 10 x64 with a NUC or similar machine using i5-4250U with older Intel HD Graphics 5000 (Drivers+Windows Updates all on latest versions)
• See Windows becoming completely unresponsive/unusable
• Only way to exit is removing power from the NUC/machine

Using an older Sciter-based client version or the 1.2.1 x86 Sciter version of the client works without this problem.

Thanks for looking into it and your work. :)

Expected Behavior

Client working without freezing the machine.

Operating system(s) on local side and remote side

Windows 10 x64

RustDesk Version(s) on local side and remote side

1.2.1

Screenshots

N/A

Additional Context

No response

[rustdesk]

Frankly, nothing we can do from our side except waiting for flutter update，it is also impossible for us to reproduce such case.

[rustdesk]

please stick to sciter version for the time being, let us keep watch

[axbmcuser]

@rustdesk

Thanks for your reply! :)

• Is this a known issue with flutter?

I'd propose

1) Releasing a x64 sciter client version until a fix happens in regards to a updated flutter version. Or is compiling the latest version with x64+sciter not possible due to anything?

2) Adding a FAQ remark which warns users about this existing issue. (If it would be a small issue like being a bit slow i'd not bother - but since it's an instant full machine freeze/crash, it should be very recommended to add a remark)

Thank you again!

May I ask if you are using the FLUTTER version downloaded from here, as I am using the same version and everything is working fine? If you compiled it yourself, could you please provide me with the steps so that I can try to reproduce this issue?

[axbmcuser]

@xiaodusx1 Sure! The issue occurs under described circumstances with every flutter based windows client version downloaded from: https://github.com/rustdesk/rustdesk/releases

I tested it since the earlier flutter nightlies up to latest v1.2.1 with identical results.

What hardware did you use while trying to reproduce?

I guess it may be a bug+incompatbility flutter has with the specific IGP Intel HD Graphics 5000.

Thanks again.

Thanks for the links. I read through them for informational purposes.

Since it's unlikely the flutter-desktop-issues situation can be resolved in the short term, i would again refer to my two suggestions from above:

• Offering a x64 sciter client version (besides the already existing x86 sciter version)
• Adding a FAQ remark/warning ...for the time being

At the moment, even users which are interested in the commerical plan offerings, are downloading the flutter version without expecting that a stable client version would potentially crash their machine completely. Above mentioned suggestions would mitigate the situation for both free and commercial users and essentialy avoid users having a wrong bad first impression of the product.

In my many years of passion for product/QA-work, i can safely say that having a software which is provided as a regular (non-nightly) release crash this way will turn away users with an unnecessary and avoidable feeling of the software being "not ready to use" which would be a shame since the core of RustDesk is so great.

Thanks again for your time and having the discussion. Much appreaciated.

i5 7600k+GTX1066+win10,too.
1.1.9 is fine.

[rustdesk]

How about run with env LIBGL_ALWAYS_SOFTWARE=1?

[ThaCheeseBun]

Also happening for me on 1.2.2 and 1.2.1, sciter build works fine. Ryzen 3600x + RTX 2070 + Win 11

env variable makes no difference for me at least

[rustdesk]

@21pages please build a simple flutter demo app, and let them try. We need to figure out what feature of Flutter we are using cause this problem.

[21pages]

https://github.com/21pages/test/releases/download/test/simple_flutter_demo_windows_x64.zip This is a simple flutter demo, please test if it can run.

https://github.com/21pages/test/releases/download/test/simple_flutter_demo_windows_x64.zip This is a simple flutter demo, please test if it can run.

@axbmcuser @ThaCheeseBun can you try out this and let us know?

[axbmcuser]

@rustdesk Yes, i'll test asap and provide feedback.

[rustdesk]

@axbmcuser any update?

[Morkph]

Hi @rustdesk , you asked me to reply here based on my recent reddit post. In my case the flutter client does not freeze my computer, but I get a white screen instead. Sciter version works.

Let me know how I can help you debug this issue.

[Morkph]

@rustdesk I have downloaded and tested the flutter demo you uploaded 2 weeks ago. It works, After 13 successful increments, I thought I was enough.

[rustdesk]

@Morkph thanks, we will generate more demo for your test. @21pages please generate more demos

[21pages]

@Morkph Thanks for your feedback. Can you try running "--cm" from command line and let me know if you see a connection manager window briefly appears on the top right, similar to the video below? If "--cm" freezes your system, please try "--install", it should show install page.

[Morkph]

@21pages When I use start rustdesk-1.2.3-x86_64.exe --cm I see something happen very briefly (I think it starts and ends instantaneously). With start rustdesk-1.2.3-x86_64.exe --install I get to see the following (white) screen:

[rustdesk]

@Morkph Great, you gave us a very good clue. We will split --install out, and let you test different versions to find the cause.

[21pages]

https://github.com/21pages/test/releases/tag/flutter_windows Could you try these two plugin demo? The most likely cause is these two plugins, I'll split --install ASAP.

[Morkph]

@21pages desktop_multi_window_example ->

windows_manager_example ->

Both appear to be working as intended (you be the judge ;))

[rustdesk]

Thanks, @Morkph

[21pages]

https://github.com/21pages/test/releases/download/flutter_windows/rustdesk-callShowInC-install.exe @Morkph Could you try this one? Click and run, the logs will be printed in D:/log.txt.

[Morkph]

@21pages log.txt output: log.txt

Similar white screen, though the rest appeared to be black, not translucent.

[21pages]

Thanks, install body Ok not printed out, I'll build another one

[rustdesk]

Good job.

[21pages]

https://github.com/21pages/test/releases/download/flutter_windows/rustdesk-RemoveResizeArea-RemoveBodyCotent-install.exe @Morkph Could you try this one? Run it in git terminal and you can see the log, or see the log in file(the log in file may miss)

[rustdesk]

Sorry, running from cmd.exe can not print out all logs.

[21pages]

https://github.com/21pages/test/releases/download/flutter_windows/rustdesk-RemoveResizeArea-RemoveBodyCotent-TerminalAttached-install.exe

https://github.com/21pages/test/releases/download/flutter_windows/rustdesk-1.2.3-RemoveDesktopTab-install.exe

Ignore the last one, click and run this one, a terminal will pop up.

[Morkph]

@21pages Sorry, I am working in the background as well. ;)

When running rustdesk-RemoveResizeArea-RemoveBodyCotent-TerminalAttached-install.exe, I get to see the following (familiar white screen):

When running rustdesk-RemoveResizeArea-RemoveBodyCotent-TerminalAttached-install.exe I get to see the exact same thing.

You have posted more messages above. I have installed git in the meantime, but the file you wanterd me to show the log of, leads to a 404.

[rustdesk]

@Morkph Thanks for your time, you gave me big clue again. It seems the flutter engine does not get started at all.

[Morkph]

@rustdesk @21pages When you want me to use git (I have installed it now) to execute one of your experiments, I get the following message: $ rustdesk-RemoveResizeArea-RemoveBodyCotent-TerminalAttached-install.exe bash: rustdesk-RemoveResizeArea-RemoveBodyCotent-TerminalAttached-install.exe: command not found

I should be in the correct directory, when I type dir -l, the file shows up.

Probably this is because I am inexperienced / installed git using the incorrect options (just clicked on accept on the infinite list of options)?

[21pages]

What about ./rustdesk-RemoveResizeArea-RemoveBodyCotent-TerminalAttached-install.exe?

[rustdesk]

You missed ./, this is linux style.

[Morkph]

@21pages @rustdesk thanks ;)

$ stdcout test1 stdcerr test1

Are the lines I get to see.

The new log: log.txt

[21pages]

@Morkph Could you ensure this program? (helloworld is the simple demo), no need to see the log this time. https://github.com/21pages/test/releases/download/flutter_windows/rustdesk-runner-helloworld-ui.exe can't show normally?

[Morkph]

@21pages

Info from git window:

White screen again:

[21pages]

Thanks for the confirm

[21pages]

https://github.com/21pages/test/releases/download/flutter_windows/rustdesk-zero-plugin.exe @Morkph This program still use rustdesk runner (not helloworld's), but remove all plugin dependencies

[Morkph]

@21pages shows the famous white screen.

[21pages]

Let's go deep

[21pages]

@Morkph Could you help to confirm these 2 programs? If show nothing after click, kill it in task manager. https://github.com/21pages/test/releases/download/flutter_windows/rustdesk-helloworld-runner.exe can show normally? https://github.com/21pages/test/releases/download/flutter_windows/rustdesk-helloworld-runner-callCoreMain.exe can't show normally?

[Morkph]

@21pages rustdesk-helloworld-runner.exe -> rustdesk-helloworld-runner-callCoreMain.exe -> Didn't show a new window

[21pages]

the white window

It should show, I don't know what's wrong, let me figure it out,

Didn't show a new window

Kill rustdesk in the task manager, then click it, it will show, but abnormally.

[Morkph]

@21pages rustdesk-helloworld-runner-callCoreMain.exe ->

[21pages]

@Morkph Could you confirm this? https://github.com/21pages/test/releases/download/flutter_windows/flutter_build_windows_MD.zip https://github.com/21pages/test/releases/download/flutter_windows/flutter_build_windows_MT.zip MD normal MT white screen?

[Morkph]

@21pages Did not run from within git.

flutter_build_windows_MD -> Does not show me anything, but appears to be running in taskmanager.

Killed rustdesk.exe in taskmanager

flutter_build_windows_MT -> -> Does not show me anything, but appears to be running in taskmanager.

2nd attempt to run flutter_build_windows_MD -> Now I get to see

[21pages]

Please kill it in taskManager, and try another click
