ZDoom

Scroll down a bit in this forum: https://forum.zdoom.org/viewforum.php?f=2

Past the subforums, you'll be able to find the "New Topic" button to make a generic bug report that doesn't fit into any of the categories.

Like software, and like sound, and like vanilla.

This has nothing to do with OpenGL, though.

Yup, I'm able to reproduce this. The credit screen looks like pic 1 in 3.7.2 but like pic 2 in gzdoom-x64-g3.8pre-206-g78c0b7f23.

BTW, when summoning explosions to knock yourself back, type "god" at the console otherwise you will die with the first explosion but probably not have been knocked back far enough to enter the portal.

How to reproduce:
1. "map credits"
2. "god" and "summon explosion" many times in order to get into the portal, or wait until the credits pass and enter it

I'm using GZDoom from the new_level_refactor branch
