Can you please file a new bug upstream to https://bugreports.qt.io describing
this issue?

They may ask you to try Qt 5.12, you can do this using the packages from
experimental or upstream installer.

I'm very sorry for the error.  I am running the latest Buster for 
everything.  The problem I'm experiencing sounds an awful lot like the 
description of that bug, so I assumed the fix hadn't been implemented in 
Debian.  If it has, then it must be a different problem.  (Or the fix 
isn't complete, or something.)


I've just confirmed that when I set the scaling to 1, the problem goes 
away.  When I set the scaling to my preferred setting, 1.1, the problem 
is rampant.

The fix you linked to is already applied in our package since qtbase
5.11.1+dfsg-5 upload.

What version of libqt5gui5 do you have installed?

If it is the latest version in Buster then maybe it is a different bug?

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:
https://phabricator.kde.org/T9244

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