When used with qt 5.6, kwin ignores the KDE font settings. Reproducible: Always Steps to Reproduce: 1. Change "Window title" font settings to something distinctive 2. Install qt 5.6 (in my case, from Arch testing repo) 3. Restart kwin Actual Results: Window titles are in a generic sans font with point size 11 or 12. Expected Results: Window titles should be in font set above
which decoration?
All decorations, but I was using Papirus Dark (Aurorae).
does "all" include the breeze decoration?
I think so (I downgraded back to qt 5.5.1 as there were other issues with the Qt Style settings in System Settings being ignored (all applications were using Breeze), and a similar font size issue in the application launcher (I have my DPI set correctly, and normally use size 6 fonts).
> Qt Style settings in System Settings being ignored Sounds like a general bug in the QPA or the QPA not being loaded at all (ABI mismatch??) Please return to this if it's still a problem and one can inspect what's going on. It's hardly a specific bug in KWin (which just forwards the QFontDatabase font)
That would explain it, given the KDE packages in Arch are compiled against Qt 5.5.
(In reply to beojan from comment #6) > That would explain it, given the KDE packages in Arch are compiled against > Qt 5.5. frameworksintegration (with Plasma 5.6 also plasmaintegration) must (!) be recompiled against the new Qt version. Distributions should know that, please remind your distributor about that.
