--- Comment #8 from Greg Varsanyi <gvarsa...@gmail.com> --- (In reply to David Edmundson from comment #5) > For Case #1: > - qt now scales up font DPI for some reason, you can counter that by > explicitly also setting > QT_FONT_DPI to be half/double (not sure which way round it is) > > For Case #3 > > Since Plasma 5.5 we do have code to disable internal high DPI managing on > Qt5.6 > > However, it requires kwin/plasma also be *compiled* with Qt5.6 > > #if (QT_VERSION >= QT_VERSION_CHECK(5, 6, 0)) > QCoreApplication::setAttribute(Qt::AA_DisableHighDpiScaling); > #endif playing with QT_FONT_DPI gets me the closest. a combination of QT_FONT_DPI=96 and QT_DEVICE_PIXEL_RATIO=2 (and not setting/unsetting any new Qt 5.6 env vars) gives me consistent look and feel across the *apps*, but not plasmashell and kwin - they go half sized. it would seem that plasmashell and kwin read the font dpi value and apply that literally as pixels. that can also be mitigated by starting these two (and only these two) with QT_FONT_DPI=192. So, using a deprecated and a falsified env var - with some exception handling - mostly gets us there. -- i wonder why did you guys decided to disable the native scaling. -- You are receiving this mail because: You are watching all bug changes.
