--- Comment #3 from bbkr <b...@post.pl> --- I found that this issue is caused by QT_SCALE_FACTOR_ROUNDING_POLICY=RoundPreferFloor I've started to track back every change I made from vanilla Arch + Plasma installation and at some point I was fixing jagged fonts in Kmail when HiDPI scaling is used by setting this variable globally. When Kate is ran with QT_SCALE_FACTOR_ROUNDING_POLICY=PassThrough the popup texts are always visible. I'm leaving this isue open for you to decide if it is a bug (application should work regardles of QT scaling used) or not (only default scaling is supported and tested). -- You are receiving this mail because: You are watching all bug changes.
