Graphic Issues when viewing sheets

[Drumhavoc]

Describe the bug
When opening a sheet the first page goes blurry. After turning to the next page (clear) then returning to the first page, it will usually be all clear as well. This happened with different files. Happens in landscape and portrait mode

I'll try to resolve this soon. However first priority will probably be to implementing new features.
