SUMMARY Since updating to Plasma 5.17.5 I have scaling issues: Forced-DPI: 144 and Scaling: 1.5 * Systemsettings is fine, but Dolphin looks liked scaled to 2.0 Forced-DPI: 96 and Scaling: 1.5 * Everything is way too small like scaling 1.0 I will try to revert the update and switch back to the stable branch of Manjaro, but maybe others on Arch have the same problem and would like to share their experience. SOFTWARE/OS VERSIONS Operating System: Manjaro Linux KDE Plasma Version: 5.17.5 KDE Frameworks Version: 5.66.0 Qt Version: 5.14.0 Kernel Version: 5.4.8-3-MANJARO
Downgrading "resolved" the issue for me: Operating System: Manjaro Linux KDE Plasma Version: 5.17.4 KDE Frameworks Version: 5.66.0 Qt Version: 5.14.0 Kernel Version: 5.4.6-2-MANJARO It's about this update: https://forum.manjaro.org/t/testing-update-2020-01-08-kde-git-pamac-9-3-firefox-72-plasma-5-17-5-haskell/118443
I have the same problem on my system with display scale factor 1.2. Operating System: Arch Linux KDE Plasma Version: 5.17.5 KDE Frameworks Version: 5.65.0 Qt Version: 5.14.0
I also have this problem on Arch and believe that Plasma no longer sets and respects env QT_AUTO_SCREEN_SCALE_FACTOR=0 Running "QT_AUTO_SCREEN_SCALE_FACTOR=0 Dolphin &" fixes the issue for that particular app but there is no way to set it globally. Tried with ~/.profile, ~/.config/plasma-workspace/env/env.sh, and ~/.xinitrc Doing "export QT_AUTO_SCREEN_SCALE_FACTOR=0" on Konsole/shell sets the env but it does not affect the applications. Using this variable in /etc/profile results in Plasma not starting at all and going back to SDDM. Thank you.
