When I start kmail with QT_STYLE_OVERRIDE=breeze everything is OK.

Comment 2 Dmitriy 2020-08-22 08:22:22 UTC

As an addition I'm running Intel integrated video card here.

Comment 3 Laurent Montel 2020-08-22 09:12:54 UTC

Hello 
if it works against breeze it's a kvantum bug.
Please report to them.
Thanks
