Game: Ground Control, version 1.0.0.5, crack for version 1.0.0.7 (versions have
no effect on this issue)

***Problem***:
Some objects become invisible at random times. When this happens, shadows still
work properly. Often only certain parts of an object become invisible, like
only chassis of tank. This doesn't happen with visual effects, like lights and
fire. Camera angle has some limited effect on the moment when this happens.

I am running the game in hardware rendering mode. (Game also has software
rendering mode, but only for 640x480 resolution. Some similar glitches appear
in software mode too)

According to appdb, this has been happening forever and is not a regression.
The game uses directx 7. Logs attached.

***Additional details***:
During installation, the game asked to install directx 7.0a, which I clicked
no. Also tried clicking yes, but it has no effect. No dll overrides, winetricks
or anything was used.

The game also suffers from input slowdown at certain times, but it's probably a
different bug.

Also, this game is a free download now, so you can try yourself if you wish.
