OBS Crash – glGetError 0x505 with AMD gpu

[lulou]

Hello Everyone,
I custom compiled obs-linuxbrowser with cef-minimal on archlinux. I used NexAdn's packages on AUR. But OBS crashes when adding the obs-linuxbrowser to a scene.

I am on a Ryzen 2400G, with amdgpu finally working.
All other modules/filters work properly.

Any ideas?

The X11 connection broke (error 7). Did the X11 server die?

If I understand it correctly, this error means opengl runned out of memory.
I have 7GB of RAM and assigned 1GB of VRAM (Testest with 4GB VRAM, same error).

Thank you.

This seems to be a Qt-related error (OBS Studio uses Qt). As we are not using Qt directly, but rather make OBS create the properties window for us, there should be nothing we can do about it, but if you know for sure it is caused by our code, please let me know.

Linuxbrowser utilizes Chromium Embedded Framework (and therefore a Chromium browser) to render the websites. It might be the browser instance which is taking up too much memory (probably not VRAM), but I don't know for sure if that's possible as the error has to do with Qt, which is being used by OBS, not CEF.

Added another 8GB of RAM. Still same error.
This time even KDE crashed completely.

Currently I recompile everything (even CEF) from scrach with debug enabled. Maybe I can get more information from there on.

Compiled obs master with linuxbrowser master. Now I get constant KDE/X11 crashes.

Unfortunately, I can't reproduce these errors using current cef-minimal (updated today) and obs-linuxbrowser master branch.

[lulou]

Ok, thanks for the information. Do you use an nvidia graphics card?

[NexAdn]

currently, GTX 960 with proprietary drivers and NVENC

[lulou]

It seems this is amdgpu related. Posting more logs when i finished compiling in debug. Thank you.

[lulou]

So I installed windows build 15xxx, installed chrome and windows BSOD'ed. Windows current build works. This is deffinately a amdgpu error. You can close this.

I dont know weather google will develop aditional driver hacks or its completely resolved differently.

Disabling all hardware accelerations did not help either.

[NexAdn]

Okay, thank you four your information. I will add this to the known issues.

Sorry for opening this issue again, but upon getting the same error message and not being able to use it, all I did was install cef-minimal and it's working fine now. Running fx-8320E and Rx480 8GB, so it's not an AMD's fault after all! (It could be a fix in the CEF tho.)
