--- Comment #10 from Ilya Fedin <fedin-ilja2...@ya.ru> --- Try any distro build of Telegram Desktop (official builds patch Qt to work around the bug) on a KDE X11 session with fractional scaling factor (e.g. 1.25). The app is full of 10 year old code, written before Qt got HiDPI support, it has integer devicePixelRatio support thanks to macOS but no fractional devicePixelRatio support. Application uses QApplication::setHighDpiScaleFactorRoundingPolicy(Qt::HighDpiScaleFactorRoundingPolicy::RoundPreferFloor) to tell Qt about that but given that KDE uses this user-override environment variable (instead of the proper way) to tell the scale factor, this setting gets ignored by Qt and application UI is broken. -- You are receiving this mail because: You are watching all bug changes.
