Quit screen looks with wrong resolution/viewport on Exit. Everything else works fine (in-game, menu, intro etc.). Tried also to force res but nothing fixes quit screen.
Notice that quit screen is ok WITHOUT dgVoodoo using (sloooow) Windows built-in ddraw emu:

With dgVoodoo looks like is zoomed-in (using desktop res 2560x1600 despite the screen res is 640x480?), showing top-left corner:

dgVoodoo 2.83.2, Win 11 23H2 (22631.4317), 4090 laptop with 551.86, 2560x1600 16:10 125% DPI 10bit.
In-game settings set to fullscreen 640x480x16.

Aaargh... It was an (Advanced) Optimus issue: since I use desktop in Advanced Optimus mode (iGPU + switch to dGPU when needed) it ran probably only on Intel iGPU: I forced dGPU from Windows 11 Graphics settings for jazz2.exe, et voilà! Credits screen on quit is fixed and not badly proportioned out of screen anymore! Probably a Intel iGPU video drivers incompatibility I'd say...
