Works okay with integer scaling though? This bug does not occur with scale factor 1. I can't test scale factor 2 because my display is 1080p. This bug only occurs with scale factor 1.2 when I set the icon size to 128px. You can still use 2x scaling with your 1080p screen; things will just be small. :) Alternatively you can do it only for Dolphin by running `QT_SCALE_FACTOR=2 dolphin` Created attachment 120803 [details]
screenshot of scale factor 2
With scale factor 2 sometimes the previews are fuzzy, sometimes they are blurry, sometimes they look fine. It depends on the icons size.
Can reproduce. They should be much sharper than they are. Created attachment 120805 [details]

It's not only the previews of files inside folders, but also the preview in the right details panel, when using scaling 1.5.
(I guess this is related? Otherwise I may open another report.)
