Summary	08539: UI: Thumbnail preview is blurry on first load
Description	The thumbnail preview is blurry in the MAME UI on first load, as illustrated in the attached photos. The height also seems to be smaller. When I navigate away from the game and come back, it's back to being crisp again.

No.20985 Robbbert Senior Tester Dec 30, 2022, 23:18	As a further note, if you leave it at "No image available", quit MAME and start again, that message is huge and blurry. Again, moving the selection fixes it.
