Skybrush Live Going blank after starting

[bytesByHarsh]

Just after starting the application, it loads for a few seconds but then the screen turns white.

Version: 2.8.1 System: Ubuntu 20

Hi, @bytesByHarsh! I'm fairly certain that this is caused by an Electron / GPU driver version conflict, which results in the crash of the renderer process. Could you please complete the following steps in order to help diagnose and resolve issue?

• Check if your drivers are all up to date
• Share the make / model of your GPU
• Run the application with / without hardware acceleration enabled
• Run the application from a terminal window and share the output

Hi @isti115 I have NVIDIA GeForce RTX 3070 in my system, and all the drivers are up to date.

After running in the terminal I am only getting the following line:

MESA-INTEL: warning: Performance support disabled, consider sysctl dev.i915.perf_stream_paranoid=0

I am not sure how to test with / without hardware acceleration enabled, if there is any specific command to do so I'll try it out.

Hmm, just to make sure that I'm on the right track, could you please run the application with the developer tools enabled (pass the -d command line flag), and check if:

• The "Devtools was disconnected from the page. Once page is reloaded, Devtools will automatically reconnect." message appears after the main window goes blank?
• Pressing CTRL+R (refresh) while the devtools window has focus temporarily resurrects the user interface?

Also, some further (maybe unrelated, but good to know) questions:

• Does your system have a CPU with an integrated GPU?
• Is your desktop environment running on Xorg or Wayland? (Hopefully a simple echo $XDG_SESSION_TYPE should give you an answer, if not, here are some more ways to check.)
  • If the desktop environment is using Wayland, please check if Live is running under XWayland!

Update: I have created an experimental build that has Electron 28 included, which should enable the usage of the ELECTRON_OZONE_PLATFORM_HINT=wayland environmental variable. (It would've required setting --ozone-platform=wayland previously, which didn't get passed through to Electron when launching the AppImage.) You can download it from the release assets here.

As far as I can see from the screen recording, you seem to be running the default Ubuntu desktop environment, Gnome. If you can get it to run under Wayland[^1], please try the experimental build it in the terminal with this environmental variable set: ELECTRON_OZONE_PLATFORM_HINT=wayland Skybrush-Live-v2.8.1-8-g66c704fb.AppImage
