Wine 4.11 default log

When CSMT is enabled, certain UI elements (e.g. text fields) are highly slowed
down, to the point of them having severe input lag of a few seconds or simply
not reacting at all. When exiting the game, the credits render a frame only
every few seconds, with large skips inbetween.

Both of those problems disappear when disabling CSMT.
