      Hi

       

      I have repaint issues when I use fractional display scale in KDE Plasma, watch my screencast please. It explains better.

      Two reports about this issue were created in KDE tracker.

      https://bugs.kde.org/show_bug.cgi?id=392028

      https://bugs.kde.org/show_bug.cgi?id=388265

       

      KDE developer Hugo Pereira Da Costa  said it's a QT bug:

      "This is unfortunately an upstream bug. Breeze itself has no control over clip areas. The same issue appears with other widget styles, and in fact there was a duplicated bug about this some weeks ago (which I cannot find again though ...)

      This will have to be reported to QT."

       

      Thanks.
