--- Comment #7 from Nate Graham <n...@kde.org> --- Git commit a21bc11fe11651f6d211489ebfc8435cef877194 by Nathaniel Graham. Committed on 16/03/2018 at 22:26. Pushed by ngraham into branch 'master'. Fix text scaling with non-integer scale factors when PLASMA_USE_QT_SCALING=1 is set Summary: When `PLASMA_USE_QT_SCALING=1` is set, Plasma uses native Qt scaling. This works fine for integer scale factors, and fixes a lot of bugs (see [[https://bugs.kde.org/show_bug.cgi?id=356446|Bug 356446]]) but it introduces a new one: with non-integer scale factors, text becomes blurry and pixellated because of a bug in `Text.NativeRendering`: https://bugreports.qt.io/browse/QTBUG-67007 QQC2-desktop-style forces the use of `Text.QtRendering` rendering for non-integer scale factors, successfully working around the problem. But PlasmaComponents QML objects don't implement the same workaround, so we see the issue in Plasma. This patch fixes that, and gets us one step closer to being able to use Qt scaling in Plasmashell. There is no effect when `PLASMA_USE_QT_SCALING=1` is not being used. FIXED-IN 5.13 Related: bug 391691, bug 384031, bug 391695, bug 391694, bug 385547, bug 391692, bug 356446 Test Plan: Before: `PLASMA_USE_QT_SCALING=1` set, 1.2 scale factor: Plasma text looks awful: {F5749797} After: `PLASMA_USE_QT_SCALING=1` set, 1.2 scale factor: Plasma text looks amazing! {F5749798} Note that we still get sub-pixel anti-aliasing and good kerning. There appear to be no layout regressions. Without both `PLASMA_USE_QT_SCALING=1` and a non-integer scale factor set, there is no visual change compared to the status quo.
