--- Comment #10 from Mark K markk@clara.co.uk 2012-01-28 02:55:31 CST --- I'll re-test with Wine 1.4rc1 and various Nvidia driver versions in a few days time.
In the changelog for 1.4rc1, bug 20089 "Theme Park World: Loading screen displayed wrong on GeForce 4 MX" and bug 29605 "Theme Park World: Lobby screen is black on GeForce 4 MX" are listed as fixed. That (hopefully) could mean the variety of graphics issues I've seen with Wine and various Nvidia driver versions are fixed.
The reporter of those bugs was using a Geforce 4MX with Nvidia driver v96. That chip is significantly older than my Geforce Go 7300, but the Go 7300 does work with the v96 driver (as well as the other versions provided by Ubuntu; 173, 280 and 285). The Geforce 7 generation is the last chip supported by the v96 driver. If you have access to a Geforce 7-series card it might be helpful for testing purposes.
