Hi,
I just checked again the HIDPI support of Kate/KWrite on Windows and
it "sucked".
It seems we never properly did setup the stuff to auto-scale, e.g. the
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling, true);
call was missing, we only had the
QCoreApplication::setAttribute(Qt::AA_UseHighDpiPixmaps, true);
part that we sprinkled in most of KDE's things in the past.
I now rectified that for Kate/KWrite, shall we do this for all our
applications?
Hi,
This is wrong to set it manually, cause it's equivalent to setting
QT_AUTO_SCREEN_SCALE_FACTOR=1,
which in turn conflicts with setting QT_SCREEN_SCALE_FACTORS (Scale
Display button in KScreen module).
