Client renderer random crashing with L-100 error on intel integrated graphics with 5th gen intel cpu

[flynnsarcadenix]

Describe the bug
Client crashes randomly with L-100 error. Tried Alpha, Beta and Stable via AppImage with several workarounds. Tried shadowcker too.

System

• OS: Ubuntu
• OS Version: 20.04
• Environment: KDE
• Application: Appimage
• Application Version: 5.0.632

Configuration

• The user is in input group ? yes
• The environment uses Xorg ? yes
• VA API detects H264 ? And H265 ? yes

To Reproduce
Steps to reproduce the behavior:

1. Starting Shadow with allow_rgb10_configs=false LIBVA_DRIVER_NAME=iHD ./ShadowBeta.AppImage
2. Login and select display safe mode. Start Shadow and play your favourite game in non-fullscreen mode
3. Client crashed randomly with L-100 error code. Sometimes it just takes minutes and sometimes its running for hours without problems. I noticed it appears to crash more often during primetime, but i think thats just coincidence
4. After L-100 crash, start connection to shadow again.

Additional context

Crashes happen on h264 and on h265. I tried every setting possible, eg low-end config on, optimize streaming set to speed or reliability. CPU is Intel(R) Core(TM) i5-5300U with Intel Corporation HD Graphics 5500 . As its 5th gen intel cpu, i installed first installed only i965-va-driver, but it needs intel-media-va-driver-non-free too to even start. I tried both LIBVA_DRIVER_NAME=iHD and LIBVA_DRIVER_NAME=i965 .

As requested on discord my logs attached for one evening. If i recall correctly it crashed three times within roughly 4 hours or so.

So i did some more testing with help from Alex on Discord:

• running single screen only with fullscreen locked Appimage Beta does not help. Many L-100 crashes
• running shadowcker beta dual screen NON fullscreen locked does also not help. Again many L-100 crashes

But running shadowcker beta with dualscreen setup and fullscreen locked reduces the number of L-100 crashes. I now only get crashes when disabling fullscreen lock to do something on my other screen. Its annoying but for the time being it works.

I run shadowcker with the following settings:
adding to docker-compose.yml:

         environment:
+            - LIBVA_DRIVER_NAME=i965

starting with:
make start && docker-compose logs -f
