Created attachment 151291 [details] Picture Edit mode toolbar is misaligned horizontally by the factor of (I assume) global scaling with PLASMA_USE_QT_SCALING=1 1.68x scaling on the attached file
Can reproduce on Wayland, so it looks like this is a thing with Qt scaling in general, and not just on X11. For me it's actually glued to my left edge though, not off-center on the right.
Cannot reproduce with a new user, but it's possible that after the screen resolution is changed, the toolbar doesn't stay in the center position anymore.
