After login, krunner dialog is not "composited". The only way to fix it is to restart compositor or restart krunner. It was happening sometimes (very rarely) also in KDE4, however in Plasma 5 it is almost always. It is probably some race condition. Reproducible: Always Steps to Reproduce: 1. Login 2. Diplay krunner (alt+f2) 3.

Same behaviour here. It's composited only if I restart it. I've this issue since kde 5.3
I can confirm this - for me, this only happens now since my upgrade from Plasma 5.5.3 to 5.5.4 - it worked fine before. I can also confirm that killing and restarting krunner re-enabled compositing for this application for the current session.
With plasma 5.7, this behavior extended also to main panel (not so bad as krunner, however happens very often)
Does this still happen? There was a fix in KWindowSystem [1] which should have fixed this. [1] https://quickgit.kde.org/?p=kwindowsystem.git&a=commit&h=4d355569eea2fae76ed67f791db8abeec1e794f0
Currently, it works for me. However, the panel's (and krunners) opacity is so high, it's hard to distinguish sometimes if compositing is actually enabled for the panels or not. Is there a way to influence the opacity?
Works for me also. I think the opacity can be lowered by disabling "Background Contrast" in kwin settings.
