https://bugs.kde.org/show_bug.cgi?id=3D388030 --- Comment #3 from Martin Kostoln=C3=BD --- Another insteresting issue connected to thie behaviour is that sometimes su= ch misbehaving systemsettings is leaking parts of its gui through other windows even if it is under them (visual flashes). Similar issues are with e.g. kmail. I thought that is is because of qt5-webengine but I'm not so sure right now. If these apps (kmail, systemsettings5) are run with QT_QPA_PLATFORM=3Dxcb -> mentioned problems a= re gone. --=20 You are receiving this mail because: You are watching all bug changes.=
