Description Cristian Tibirna 2020-05-04 04:53:42 UTC
Currently, the slider for selecting the display's fractional scale in the "Screen Scaling" dialog can be moved from 1 to 3 in 0.1 steps.
 
As explained very clearly here
https://cullmann.io/posts/kde-qt-highdpi-scaling/
this is a bad idea, as it creates very complicated issues with float number representation as used in pixel level rendering.

The slider should have steps of 0.0625 (1/16.). Alternatively, a direct number input should be provided.
