Scale 100%

To fix the removal of adjusting toolbar icons, I tried to scale down the display on my 15.6" laptop with 1366x768 screen, but every possible scale value always produces blurry result including icons, fonts and all GUI widgets. See attached images.

KDE Plasma Version: 6.0.1

Scaling at <100 will be supported better from Qt 6.7 onwards. Otherwise it is rescaled by the compositor, which is what you're seeing here.

When will it be released for Plasma6? And will it also solve scaling down for non Qt apps? 

While waiting, is there any command line or setting to add to any config file to resize all Qt toolbar icons to small (16), because for some apps like Spectacle, open/save dialogs... there are no settings to resize their toolbar icons.

It was working last week with latest 5.27.10 even with toolbar resizing feature removed, so I suppose Plasma was reading the toolbar icons size from somewhere. I'm happy with just decreasing font to 9pt and decreasing toolbar icons to 16, instead of scaling down my whole desktop under 100% and suffering from unnecessary bugs, because most my apps as Qt based and 4 or 5 GTK apps.
