-- Information about the crash:
I'm using openSUSE Tumbleweed 20231103 with the 6.5.9-1-default arch kernel and KDE Plasma 5.27.9.
I've got a ASUSTeK Z87-PRO motherboard, Intel Core i5-4670K processor, and an AMD Hawaii PRO [Radeon R9 290/390] graphics card using the amdgpu driver.

The crash can be reproduced every time.
