Bug#924956: qt3d-opensource-src: Fractional HiDPI scaling causes serious artifacts in some QT applications
Source: qt3d-opensource-src
Severity: important
Tags: newcomer
Dear Maintainer,
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:

If this patch could make it into Buster's QT, that would be fantastic.
