SUMMARY Ksplash should show a screen with a spinner with the breath theme. In place of the screen I see a blocky square box turning around. I see this on a laptop with AMD GPU. On an older Intel haswell laptop the spinner is fine. With other themes (e.g. breeze), the spinner is fine. STEPS TO REPRODUCE Login OBSERVED RESULT Corrupted spinner appears before plasma launch is completed EXPECTED RESULT Nice looking spinner is shown and animated. SOFTWARE/OS VERSIONS Operating System: Manjaro Linux KDE Plasma Version: 6.0.4 KDE Frameworks Version: 6.1.0 Qt Version: 6.7.0 Kernel Version: 6.8.9-3-MANJARO (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 9 6900HS with Radeon Graphics Memory: 30.6 GiB of RAM Graphics Processor: AMD Radeon Graphics Manufacturer: ASUSTeK COMPUTER INC. Product Name: ROG Zephyrus G14 GA402RK_GA402RK System Version: 1.0
This would be an issue either in the Breath theme, or your GPU drivers, or both.
Indeed, seems kernel related, can be closed.
