Created attachment 139330 [details] The appearance of the panel with translucency enabled When the panel opacity is set to adaptive or translucent, the 6 pixels of the panel furthest from the screen edge always remain opaque. This does not occur on the XRender compositor backend. STEPS TO REPRODUCE 1. Choose the OpenGL 3.1 or 2.0 compositor rendering backend 1. Add a panel 2. Set the opacity to translucent or adaptive OBSERVED RESULT The 6 pixels of the panel furthest from the screen edge always remain opaque EXPECTED RESULT The translucent effect should apply to the entire panel SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Plasma Version: 5.22.0 KDE Frameworks Version: 5.38.0 Qt Version: 5.15.2
I'm seeing this on the panel and its other plasmoids/widgets. It appears on all _outer_ edges (right and top of start menu, left and top of calendar, all edges of a tooltip, right of 'add widgets'), not on edges that are touching screen border / the panel. I tried disabling Background Contrast and rebooted but that didn't help.

What happens if you clear the cache and restart plasmashell? `rm ~/.cache/plasma* ; plasmashell --replace &`
Nice, deleting the cache and restarting seems to have fixed it.
Thanks.
Had the same problem, deleting the cache solved the issue :)
