Due to a recent commit in Wine I get severe audio stuttering as well as
slowdowns in certain games. This seems to affect only a small number of games,
the vast majority of my games are still running fine. Whether these games are
buggy ones or it is indeed a problem with the patch I can't decide as I don't
have Windows installed to check how these games behave under native Windows.

275dfb83f2371a476b615b260465afb3cdf67f32 is the first bad commit

Star Wolves 3: Civil War (v1.12, Steam): audio playback is glitch-free and
performance is okay (well above 60 fps) in the menus and during the tutorial
mission. When I advance in the game or when I load a saved game I get severe
audio stuttering and framerate drops below 15 fps. This makes the game hardly
playable. If I quit playing and go back to the main menu, everything is back to
normal.
The demo for the game is protected with Starforce so it cannot be tested.

Droplitz (Steam version): this is a puzzle game. A certain sound effect is
intended to play when I create a path for the 'drops' and they make their way
to their goal. When this happens I observe the same audio stuttering and
performance drops. It lasts only for 2-3 seconds so it's not so severe.

Armored Fist 3: audio (both music and speech) are stuttering heavily and it
affects performance too. Link to the demo added to URL. There is no music in
the demo, but you should observe the problem with speech after starting a new
game.

HoverAce: the same stuttering in audio and slowdowns can be observed. No demo
available.

Terminal output doesn't show anything related.
