Issues with Mesa 24.3.x on KDE 6 Wayland with AMDGPU [SOLVED]

Hi all,

After updating Mesa to version 24.3.0/24.3.1 on my Arch Linux system, I’ve encountered severe issues when running KDE 6 on Wayland using an AMDGPU (Radeon Pro WX 7100). Specifically:

    startplasma-wayland leads to a blank screen.
    Debugging indicates that kwin_wayland starts, but plasmashell fails to render properly.
    Downgrading Mesa to version 24.2.7 resolves the issue, and everything works as expected.

Here’s what I’ve tried so far:

    Resetting KDE and Wayland configurations.
    Testing with QT_QUICK_BACKEND=software (works but disables GPU acceleration).
    Testing with KWIN_DRM_RENDERER_BACKEND=vulkan or gl, both of which fail.
    Reverting to a clean ~/.local/share/plasma (no custom plasmoids are installed).

Observations:

    vulkaninfo now works correctly after addressing Vulkan ICD issues (previously misconfigured with NVIDIA ICD files).
    Logs suggest no critical errors from kwin_wayland, but libgallium errors appeared in kernel logs with Mesa 24.3.x.
    Mesa 24.3.x introduces changes that seem to break compatibility with AMDGPU and KDE Wayland setups.

System Details:

    GPU: AMD Radeon Pro WX 7100 (Ellesmere)
    Kernel: 6.12.1-arch1-1
    KDE Plasma: 6.x
    Mesa: 24.3.x (problematic), 24.2.7 (stable)

Is anyone else experiencing similar issues with Mesa 24.3.x? If so, are there any known workarounds or patches? I’d appreciate any guidance or feedback!

Thanks in advance.

https://bbs.archlinux.org/viewtopic.php?id=301550 seems to be about the same issue

Re: Issues with Mesa 24.3.x on KDE 6 Wayland with AMDGPU [SOLVED]

Same here.

Yesterday I upgraded my system and the screen was left blank with just the mouse moving.

KDE Plasma Version: 6.2.4
KDE Frameworks Version: 6.8.0
Qt Version: 6.8.1
Kernel Version: 6.12.1-arch1-1 (64-bit)
Graphics Platform: Wayland
Graphics on board Processor: AMD RS880
Manufacturer: Gigabyte Technology Co., Ltd.
Product Name: GA-880GM-UD2H

I reviewed the logs and found that the start-up screen wasn't loading giving some serious errors on Mesa and drivers depending on that.
The main error was referring to libgallium.

I downgraded Mesa and everything worked again, without errors on the logs.

Just waiting to see if there's a new mesa version to upgrade and test.

The older GPUs seem to be forgotten... ?

Re: Issues with Mesa 24.3.x on KDE 6 Wayland with AMDGPU [SOLVED]

I have been following the bug report and 2 things are becoming clear :

- the bug is not limited to older amd videocards, but affects all gpus without support for format modifiers

- All reports sofar have been with wayland . No one has encountered this issue while running X.

Same here :
- Wayland
- AMD RX 550

Downgraded mesa to 24.2.6.1 to retrieve a functional KDE.

I confirm 24.3.1-3 fixes my problem as described with GPU radeon-pro Radeon Pro WX 7100 and 5100 series.
