screenshot (difference between pure Wine & CSMT enabled)

The issue looks much alike bug #38136, there's a difference though.

Letters & numbers are randomly(?) missing from the game (see attached
screenshot).
Wine patched with the CSMT patchset from wine-staging doesn't have the bug in
either game.

The difference: according to my testing it's a different patch from the CSMT
repo which fixes the problem in the Pac-Man game:
