Created attachment 137592 [details] Application thumbnail missing in preview tooltip Hello, in my Task Manager - icons only, the preview tooltip that should display a thumbnail of the window stays empty instead. I'm on OpenSuse Tumbleweed, XWayland session (I specify this because openSuse also has a Full Wayland one - not sure it makes any difference tho). Thanks Operating System: openSUSE Tumbleweed 20210408 KDE Plasma Version: 5.21.3 KDE Frameworks Version: 5.80.0 Qt Version: 5.15.2 Kernel Version: 5.11.11-1-default OS Type: 64-bit Graphics Platform: Wayland Processors: 4 × Intel® Core™ i7-4510U CPU @ 2.00GHz Memory: 7,6 GiB of RAM Graphics Processor: Mesa DRI Intel® HD Graphics 4400
