GZDoom 4.11.1 (from 4.10) doesn't do shadow maps?

[Sir Robin]

I just upgraded my 4.10 to 4.11.1 and I'm noticing that dynamic lights are no longer blocked by voids. It's still turned on in options, and I kept a copy of the 4.10 INI and compared it to the new one from 4.11.1. Other than the obvious (header line, version) there's a bunch of rounding errors and a few items that moved places. No real changes. I notice my mouse sensitivity changed from (2,2) to (1,2)

It works fine in the latest master

I'm still seeing this with 4.11.3a



v4.10.0 shows the shadow maps as expected


v4.11.3a does not

All the settings are the same, brand new map, no mods loaded
