--- Comment #3 from Frederick Zhang <frederick...@tsundere.moe> --- I noticed that again this is somehow related to global scale and using: QT_AUTO_SCREEN_SCALE_FACTOR=0 QT_SCALE_FACTOR=0.5 kcolorchooser ...resolves the issue (of 'cos you get super small UI on HiDPI displays tho, and the QT_SCALE_FACTOR needs to be adjusted based on your global scale setting). This reminds me another issue (bug 413577) I reported, where it could also be 'resolved' by disabling scaling for affected apps. I guess these problems may have the same root of cause but unfortunately I'm not familiar with the Qt stack at all. -- You are receiving this mail because: You are watching all bug changes.
