--- Comment #5 from Sebastian gustep12@yahoo.com --- I can confirm that with the registry setting ClientSideGraphics=N it works really well again. Thank you, thank you!!
Basically with that setting, the program is just as fast (or faster), and renders incrementally on the screen, just as it used to be under Windows XP.
With ClientSideGraphics=Y, Wine is probably duplicating the slow off-screen rendering performance that this program also experiences under Windows 7 and up.
My recommendation would be to make ClientSideGraphics=N the default as long as "Windows Version = Windows XP" is selected in the Wine Configuration. Is there any downside to this setting?
