Created attachment 142963 [details] Screenshot of the system tray panel SUMMARY On Wayland, I often see shadow gradients going in the wrong way, from transparent to dark. STEPS TO REPRODUCE 1. Open a panel from the system tray, the application menu or place or whatever. OBSERVED RESULT The shadow is in the wrong direction EXPECTED RESULT Shadow should go from dark to transparent. SOFTWARE/OS VERSIONS Operating System: Manjaro Linux KDE Plasma Version: 5.22.5 KDE Frameworks Version: 5.87.0 Qt Version: 5.15.2 Kernel Version: 5.10.70-1-MANJARO (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i5-8250U CPU @ 1.60GHz Memory: 7.6 GiB of RAM Graphics Processor: Mesa Intel® UHD Graphics 620 ADDITIONAL INFORMATION As far as I can see, the direction is only wrong on the top and right side of panels. The shadows behind windows look fine.
Fixed in Plasma 5.23, thank goodness. *** This bug has been marked as a duplicate of bug 439408 ***
