QT has had a bug which caused major artifacts in QT applications, for example Kate, Kwrite, Konsole, and probably many others. It only is an issue when non-integer scaling factors for HiDPI are used. At least for me, this makes Kate very difficult to use. The bug was fixed on this page: https://bugreports.qt.io/browse/QTBUG-66036 Comment #6 contains the fix, which is quite small. You may have to click the "X older comments" link to get this comment to appear. It was too late to make it into QT 5.11, sadly, but there is (or was?) talk of cherry-picking the patch into 5.11: https://phabricator.kde.org/T9244 If this patch could make it into Buster's QT, that would be fantastic. -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.19.0-2-amd64 (SMP w/8 CPU cores) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE= (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled
