Created attachment 126931 [details] The window overflows the title bar SUMMARY The window overflows when using Aurorae theme engine together with Nvidia proprietary display driver. STEPS TO REPRODUCE 1. Change the window decoration theme to McMojave Light 2. Start any application OBSERVED RESULT The window overflows the title bar EXPECTED RESULT The window should be within the title bar SOFTWARE/OS VERSIONS Linux/KDE Plasma: openSUSE Tumbleweed 20200318 KDE Plasma Version: 5.18.3 KDE Frameworks Version: 5.67.0 Qt Version: 5.14.1 Display Driver: Nvidia 440.64 Window Decoration Theme: McMojave-Light, or Breezemite ADDITIONAL INFORMATION This bug does not exist when using Intel/Nouveau drivers. See the screenshot for details.
>This bug does not exist when using Intel/Nouveau drivers. That sounds unlikely. Is it the same machine? Does it affect every window when the bug exhibits itself? For the whole session? >Window Decoration Theme: McMojave-Light, or Breezemite And all Aurorae themes are affected? Does toggling compositing (alt+shift+f12) make a difference?

Yes, it affects every window for the whole session. I can reproduce the bug on at least three machines using Nvidia display driver. However, they are all in openSUSE Tumbleweed. > > >Window Decoration Theme: McMojave-Light, or Breezemite > > And all Aurorae themes are affected? I have tested a few Aurorae themes. It seems all of them are affected. - Breezemite - Breezemite_dark - McMojave - McMojave-light - Qogir-light - Sweet-Dark > > Does toggling compositing (alt+shift+f12) make a difference? The bug persists. You can find the screenshot after toggling the compositing in the new attachment.
Created attachment 126932 [details] The screenshot when the compositing is turned off.
Can confirm with Kwin 5.18.90 aswell. Every aurorae theme looks like some pixels are missing maximized.

Urgh, I introduced this regression... 15af09c70a890424759b092a3597bf76ab308632 is the first bad commit commit 15af09c70a890424759b092a3597bf76ab308632 Author: Vlad Zahorodnii <vlad.zahorodnii@kde.org> Date: Wed Feb 5 11:28:50 2020 +0200
So, I think I know what is going on... The problem is that frameGeometryChanged is not emitted when the client size changes. We need a different signal for client size changes and then use it in DecoratedClientImpl.
Still, I don't get why everything works as expected with Breeze decoration.

(In reply to Vlad Zahorodnii from comment #8) > Still, I don't get why everything works as expected with Breeze decoration. It doesn't happen with Breeze decoration because it updates the borders right after the window has become maximized. On the other hand, Aurorae delays the update of window borders.
