I cannot reproduce. Can you please provide the output of: qdbus org.kde.KWin /KWin supportInformation
Sure, here you go: https://paste.kde.org/pqruzkvcq Note, I used the framework packages (5.5.0) from extra then I built kwin-git from aur, if it matters.
ok, that looks all fine and breaks my idea that the minimize animation fixes it for me ;-) No idea what's going on there.
Can you please elaborate on the screenshots? Notably: Is the issue the absence of shadows (but in the lower right), or do the solid colors (notably the blue) have sth. to do w/ it? Also: what happens if you disable blur & contrast effects? (run "kcmshell5 kwineffects" to configure) Last: what if you run kwriteconfig5 --file kwinrc --group Compositing --key GLStrictBinding true and restart "kwin_x11 --replace &"?
I used a plain color as wallpaper type so it is more evident that the shadows are broken. I followed all of your suggestions, nothing changed.
I found the cause: Switch Animation speed to instant.
(In reply to Antonis G. from comment #8) > I found the cause: Switch Animation speed to instant. ah yes, that makes sense. With instant I assume that minimize animation did nothing and triggered a not updated case.
Yes, I switched animation speed to not instant and disabled minimize animation, still happening. You were right after all!
just tested without the minimize effect and can reproduce.
Git commit c69dec566c17c5cf5b324ebde41a0c8042b4acc1 by Martin Gräßlin. Committed on 07/01/2015 at 09:53. Pushed by graesslin into branch 'master'. Use layerRepaint with visibleRect from Client::map When map is called we need to repaint the complete area including decoration shadows (e.g. might be called after unminimize). Therefore we use a layer repaint with the visibleRect. REVIEW: 121891 M +1 -0 client.cpp http://commits.kde.org/kwin/c69dec566c17c5cf5b324ebde41a0c8042b4acc1
