Hi! Plasma 5.26.0 with Qt 5.15.6 finally made it to Debian testing, and after upgrading it all I noticed that thumbnails aren't showing up in task manager (they just appear as empty instead of showing contents of windows in them).
Did anyone encounter this bug? It seems Debian specific, since KDE developers said they didn't encounter it in their set-ups. Should I report it to Debian bug tracker, or it's some kind of temporary situation due to something not yet migrating to testing properly? Thanks! Shmerl.
