2.2.11 Pre1; Sector Floor/ceiling textures break on steep equation slopes
When making a steep equation slope that is not close to the center of the map, the display of the texture on the slope can break, even if the alignment remains unchanged. This does not appear to be the case for textured slopes using the linedef actions. It also appears correctly in visual mode (in UZB).
The texture is there alright, but if you look closely you see what appears to be the texture scaled down to the point where it almost resembles noise, except it was decided SRB2 2.2.11 will not yet have texture scaling and as such no scale was set.
The following map is the simplest possible demonstration of the bug in 2.2.11 prerelease 1 (UDMF). MAP01.wad
