[Linux] Settings, and create new add-on GUI doesn't displaying

[Turelk]

When I try to open settings or new add-on menu, visually nothing happens, although in reality these menus open, but are not displayed.

Can't reproduce, sorry. Maybe a problem with hardware acceleration. What distro is that?

[St1X89]

I cant even run on Arch lol

[PenguinDOOM]

The same goes for my Arch.

That is SteamOS 3.0 (Arch Linux)

To be honest, even if I installed Arch and reproduced the problem, I wouldn't know how to fix it. Additionally, as far as I can tell, the problem appears to only happen on Arch?

I believe the problem has something to do with hardware acceleration. When opening the settings panel, it uses a CSS transform transition to animate in which makes use of the GPU. Everything else appears to be working in the video, but CSS transform transitions don't work. That is a complete mystery to me, and I have no control over it as the OS provides the WebView.

Sorry I cannot be of more help.

Hello there.
I have the same issue on Manjaro KDE and I'm getting the only error in the terminal when running the application: src/nv_gbm.c:242: GBM-DRV error (nv_gbm_create_device_native): nv_common_gbm_create_device failed (ret=-1)

I am not sure if this is helpful or anything, but if the problem is GPU acceleration (as I understand from the last comment), so is it possible to add an option to turn it off by default or to transitioning animations at least?

Try adding WEBKIT_DISABLE_COMPOSITING_MODE=1, it fixed the issue for me

Should look something like this:
LD_LIBRARY_PATH=/path/to/gmpublisher WEBKIT_DISABLE_COMPOSITING_MODE=1 /path/to/gmpublisher/gmpublisher

[WilliamVenner]

Awesome, thank you. If others can confirm this fixed the issue for them, I’ll set that environment variable when gmpublisher starts.

[Hatchet-ManDev]

I have tried the export WEBKIT_DISABLE_COMPOSITING_MODE=1 and can confirm everything now works fine.

Also I've seen another issue (may be related to Arch-based users with proprietary NVIDIA drivers) such as Failed to create GBM buffer and the line export WEBKIT_DISABLE_DMABUF_RENDERER=1 seems to solve this one, at least I have no errors in terminal now and can work with addons freely.
