[d3d8] Still Life light flickering (regression)

[WinterSnowfall]

There's some light flickering noticeable on the in-game character models that wasn't there before.

It's present with dxvk 2.4 as well, and since this is a d3d8 game it won't be possible to bisect it beyond that. All I can say is that everything looks fine with d8vk 1.0 (which was based off of dxvk 2.3.1 IIRC).

I've captured a trace which reproduces the issue anyway, so hopefully that is enough to pinpoint it.

P.S.: I've tried reverting 9e422a2 and da81466 for good measure, but neither have caused the issue.

Also most likely related to #4222, but that game no longer works on master anyway.

Was it fine with D8VK before the merge?
