Weapon sprite scaled incorrectly at 320x200
The weapon sprite appears incorrectly in Odamex in 320x200 resolution (or with vid_320x200 enabled). This is possibly caused by round-off errors in the extra scaling calculations that Odamex performs that vanilla/chocolate do not.
This thread touches on the subject as well: 0
To spot the differences, focus on the black pixels that form the outline of the top of the pistol. In Odamex, those most of those black pixels are missing due to this scaling bug.
