Overworld Map/Post-Criticals might make the screen cut off/incorrectly scaled at lower resolutions when using UE4's upscalers

This problem only appears to happen if UE4's TAAU Gen5 is enabled in the game's engine.ini, but for a better demonstration of the problem, I've recorded how it looks.
Tested on Game Pass.

Here's the lines I've added to enable the feature that causes this:
r.DefaultFeature.AntiAliasing=2
r.PostProcessAAQuality=4
r.TemporalAA.Upsampling=1
r.TemporalAA.Algorithm=1

That's interesting, so the map is a place where the issue consistently crops up? I'll have a look and see what can be done.

Hmm, if you set r.postprocessing.disablematerials to 1 it seems to help. The UE4 docs point out something that looks similar to this issue.

Also it appears to occur regardless of which UE4 upscaler algorithm is used. The offending option is simply turning on r.TemporalAA.Upsampling. I guess we've found out why the game ships with it disabled which is a damn shame since it really helps.
