This is most likely related to the installation on Platinum, on SOD 3.2, it installs perfectly now. I hope this bug will be fixed tomorrow.
I don't know what to do about it yet; it's due to zdarw.dll, which allows playing in windowed mode with 32-bit color. The bug doesn't appear if you don't minimize the game, or switch to windowed mode – it never glitches in that mode.
Well, the most important thing is not to forget about the stash when escaping....
I have SOD 3.2.
I've never played in windowed mode, but I feel like I might have to...)
