What OS? What Desktop? X11 or Wayland?

I have the below on my laptop and not having this issue. Device-2: NVIDIA GK104GLM [Quadro K3100M] driver: nvidia v: 470.239.06

Operating System: openSUSE Tumbleweed 20240310 KDE Plasma Version: 5.27.10 KDE Frameworks Version: 5.115.0 Qt Version: 5.15.12 Kernel Version: 6.7.7-1-default (64-bit) Graphics Platform: X11 Processors: 8 × Intel® Core™ i7-4810MQ CPU @ 2.80GHz Memory: 31.0 GiB of RAM Graphics Processor: Mesa Intel® HD Graphics 4600 Manufacturer: Hewlett-Packard Product Name: HP ZBook 17 G2

I am on Slackware64-current, using X11 with Openbox window manager. I have just looked back in my logs and in September 2023 I was using Nvidia driver 535.x already, maybe something that changed in the drivers between 470.x and now is causing problems with Firefox. My graphics card is an RTX 3060 and is the only graphics card in the system.

Is this something like bug 1743051?

It's possibly related to https://bugzilla.mozilla.org/show_bug.cgi?id=1743051 although I haven't noticed the exact effect shown in the videos. For me it is usually graphs that start flickering and then I know I have to restart Firefox :) I see that bug mentions EGL though, so I have just forced Firefox to use GLX instead by setting gfx.x11-egl.force-disabled to true. After a short sleep and resume test, Grafana still seems OK using GLX webrender but I will have to give it a bit longer to see what happens after some more sleep and hibernating.

Openbox window manager.

What happens in KDE or Gnome?

Unfortunately using the GLX backend didn't fix it. After getting back home this evening and waking my PC, the graphs are broken again and a strava map I had left open is also broken even after reloading.

I should be able to test with KDE to see if that makes a difference, but it seems more like a problem with the nvidia drivers and GL libraries rather than the desktop environment. Maybe using Wayland instead of X11 would fix it, but I have no idea how to do that :)

I say good old nvidia. Can't wait to hear the results of the KDE test. Why not also try another distro via live usb stick.  ;-)

I finally had a chance to close everything and reboot into a KDE Plasma (X11) session. I started up Firefox and put the PC to sleep for 1 minute using the KDE menu but I still had the same problem when waking it. I was running Firefox from a terminal this time since that was easier that trying to find it in the menus and noticed the error messages ``` [GFX1-]: GFX: RenderThread detected a device reset in PostUpdate [GFX1-]: Failed to make render context current during destroying. [GFX1-]: GFX: RenderThread detected a device reset in PostUpdate [GFX1-]: Failed to make render context current during destroying. [GFX1-]: GFX: RenderThread detected a device reset in PostUpdate [GFX1-]: Failed to make render context current during destroying. [GFX1-]: GFX: RenderThread detected a device reset in PostUpdate [GFX1-]: Failed to make render context current during destroying. ```

As for testing with a live USB, that would be a good idea to rule out any Slackware issues - but I don't think any live USB would boot with the nvidia binary driver by default? So I would need to actually install the distro and install the nvidia driver.

edit: I have just noticed that I still get the device reset messages in the terminal even in times when Firefox still resumes correctly.
