It seems that since the drag borders/corners fix in ZDoom (d3d8180 and all revisions since) that pickup and screen damages are not properly resized. (Menu dimming is, as seen in the thumbnail below)
Spoiler: Screencapsomething I do notice is it seems to be sort of the right proportions but a sizable 'chunk' off to the lower and right seems to be sawn off.
Version used to take the screenshot was development build gzdoom-g2.3pre-115-g4b8b5e3.7z
