[Help needed] DSR is causing everything to look red

[EeK]

I've been playing Blur (2010 game) on PC without any issues.

Because it's a rather old game and I have some headroom (my GPU is barely hitting 30% usage in 4K, with a locked 60 fps), I tried enabling DSR under NVCP in order to play at higher resolutions.

I went with 2x and 4x factors, with 0% smoothness (as I've used before in games like Rez). Both new resolutions appear in the game's options screen and can be selected, but, when doing so, everything becomes red. Not a full blown red screen of death, but it's like red is the only color in the RGB spectrum.

Any ideas? The game is running in full screen.

System: i7-7700K, 32GB RAM, 1080 Ti (425.11), Win 10 (1809)
Display: LG OLED B7 (3840x2160 native res)
