So, Is there any plan to match marble widget with devicepixelratio as gwenview did? I have tested a lot of workarounds such as using QT_SCALE_FACTORS, but this will carry some other ui bugs( not relevant here)

Digikam internally uses Marble to show geolocated oictures on a map. I noticed that problem too. I reported it with more details and some screenshots in this Bug #459194.

I hope it helps.
