`RadeonDeveloperPanel`: "system information unexpectedly failed to load"

[onkoe]

When launching the Radeon Developer Panel on Fedora 41, I get the following error:

The system information unexpectedly failed to load.

When reporting this, please include detailed system specifications including CPU, GPU, operating system and driver version.

Radeon Developer Panel will now exit.

The terminal also shows that the program is constantly calling into dnf, which is... weird.

I managed to click the little bug button before it crashed. Here's what that gave me:

@onkoe Please try installing AMDVLK open source driver on Fedora. Radeon Developer Panel is officially supported on amdgpu/amdgpu-pro or AMDVLK on Ubuntu, but using AMDVLK on Fedora should work as well.

@MattGuerrette Thank you for your quick reply!

I'll continue trying different combinations, but after installing the AMDVLK Vulkan driver, the crash still occurs. Alarmingly, all libadwaita windows now look like this:

Do you think giving AMDGPU-PRO a try would address these issues? If not, do you have any additional suggestions?

[MattGuerrette]

I'll take a look at what could be causing the crash on Fedora.

As for the rendering issue, that should be resolved in a future amdgpu-pro/AMDVLK driver release as it is a compositing bug in the driver for Vulkan that has been triaged and fixed. You could try forcing GTK applications to use the ngl renderer by defining GSK_RENDERER=ngl

[onkoe]

Great, thank you so much!

Did want to quickly note that the GSK_RENDERER=ngl <binary> workaround does address the libadwaita issue temporarily.

If you find any leads, or need me to test anything out, please let me know! I'm happy to whip up another install to assist you. :)
