By looking at bug #67150 it seems that the issue is that the custom scale factor was designed to only be used temporary. Could you try using setIntrinsicDeviceScaleFactor instead of setCustomDeviceScaleFactor and see if that solves the issue? It seems like we ended up using it after bug #89272 but should have been using the intrinsic one at this point.

Indeed, for the QML use-case using setIntrinsicDeviceScaleFactor seems to be the correct solution. Although, as a side note, nonetheless of the custom scale factor being a temporal value, it still feels odd that when set it is not restored when the web process crashes.
