Stream disconnection bug (error L:100) #38

Closed jame25 closed 4 years ago

jame25 commented 5 years ago

Describe the bug Stable and latest Beta client for Linux frequently dropping / disconnecting with error L:100. This problem is only occurring when free movement cursor is enabled. The client is 100% stable in 'cursor-locked' mode. Issue did not exist on the same system using the old Shadow client.

System

Additional context Graphical corruption of cursor will sometimes occur seconds before the Client disconnects. The issue can be consistently reproduced by moving (travelling by clicking) around in Google Maps 'street view' mode.

Hey, thanks for feedback, can you extend your issues with following informations :

Apologies for the delay. libva-tools (or vainfo) are not currently available as packages for FatDog64, however libva and libva-intel-driver are installed. I ended up getting the below 'vainfo' from a temporary install of Ubuntu 19.04 on the same system.

Same issue using NVIDIA patched driver:

jame25 commented 5 years ago

I note that the 'stable' client is not exhibiting this issue on the same hardware when running Ubuntu 19.04. I have tried to recreate the same environment on Fatdog64 (Mesa, Libva, Intel i965 driver) - but there is no difference - issue persists.

Since the problem will only happen when cursor is enabled and I actually click on something, can someone suggest what packages would relate to that (hardware detection?) aspect of the Shadow client?

jame25 commented 5 years ago

I believe I have now established that the current implementation of LD_PRELOAD management by the client is not going to work for all distributions. My issue was directly related to the custom SDL2 library included not being pre-loaded. Since manually doing so, cursor-locked mode now works (previously there was no cursor) and crashing has stopped.

Edit: Crashing (error L:100) is still occurring for me in windowed-mode (cursor lock off). I have to assume that this is due to a 'falling-back' to system-installed version of SDL2 when app is in that mode.

aarnoud commented 5 years ago

@jame25 once PRELOADED it shouldn't fallback, you are not alone reporting those crash linked to mouse pointer, it's most likely a bug now in the linux app.

jame25 commented 5 years ago

Okay great, thanks for the clarification.

tdeckers commented 5 years ago

I'm unable to even start streaming... on Ubuntu 19.04. Same L:100 issue... could this be the same bug? Happy to collect any info you need. Ubuntu 19.04, Geforce1050Ti

Hi there! Wooops we forgot to answer you :x

Is it still happening? Do you use the AppImage? Can you make sure that the vainfo returns correctly?

Yes, issue persists with latest beta AppImage (v2.15.7) and vainfo is correct. AppImage works without crash when in full-screen mode.

I just noticed some var/log messages related to the crash, if they offer any insight.

when using NVIDIA and patched vdpau (see: https://gitlab.com/aar642/libva-vdpau-drive), it's common issue, but if it still happens on intel, please re-open.

Since yesterday, I have the same problem. I was on 19.04, so after reinstall 18.04, it's the same. L:100 allways. Works on my friend windows laptop on same connection.
