When you start a new campaign or scenario there are 8 command icons on the main
interface. The second icon from the bottom in the row is the control panel
where you can change resolution to 800X600. However, choosing 800X600 will
result in an immediate crash. (After crashing you may need to remove
rt2_tsc.CFG from the game directory else the game won't start normally next
time).

This happens since Wine-8.0-rc1. Previously, a the game changed resolution
correctly.
The result of the regression test:
