I remember this being an issue in an earlier version of Doomsday (1.9.10 I believe), where the secret exit switch in E3M6 wasn't even visible. While it is visible now, I noticed that it is still positioned too low compared to where it is in Vanilla Doom. I attached two screenshots comparing the position of switch between Chocolate Doom and Doomsday.

Fixed|Renderer: Lower texture alignment in E3M6

This is perhaps an uncommon situation, where there is a switch on the front lower texture, but the back sector ceiling is higher than the front ceiling.

For future reference, the problem is likely around walledge.cpp:323, and pertains to material origin calculation of the lower wall section of a line with the lower unpegged flag.
