That's an issue in Qt. If you change your font to some font that doesn't have broken font metrics in Qt (eg. DejaVu fonts) it will fix this.
Thank you David. Do you know if there is some bug report about this issue in qt bug tracker?
Yes, but it was closed as invalid: https://bugreports.qt.io/browse/QTBUG-52316
Use QFontMetrics::boundingRect().width() instead of QFontMetrics::width()
Bug 401008 seems related/duplicate.
I can't confirm this bug anymore. Operating System: Arch Linux KDE Plasma Version: 5.15.3 KDE Frameworks Version: 5.56.0 Qt Version: 5.12.2
Forget. I use Roboto fonts, but the bug persists when default font settings are used.
Still happening?
cannot reproduce on Arch and neon unstable.
Excellent.
