Seemingly random frame drops in windowed mode

[ks202005]

I'm running the game in ddraw windowed mode per the instructions on the wiki, and I'm getting weird frame drops that come out of nowhere. They last half a second or maybe a full second, with the music unaffected but the gameplay seems to be frozen. I'm not adjusting the framerate from the default of 30 either. This messes up combos pretty badly. Does anyone else have this issue? Could it just be an effect of the windowed mode implementation?

I'm using an AMD Radeon RX 580 in case that makes a difference.

windowed mode is not a part of this patch. check if hangs are still there without ddraw.dll. you can try other ddraw wrappers that may work better than the mentioned one (ddrawcompat, dgvoodoo2, maybe others)
