#331 Inverted Colors when Alt-Enter to fullscreen

graphics (66)

Everytime I use Alt-Tab to enter fullscreen mode, the colors become inverted in whatever program is up. If I am at the prompt, the blue background from the "Welcome to DosBox" becomes red. If I have a game up (I.E. Warcraft), the colors are all inverted. I have to be in fullscreen and then open the game. It becomes annoying when I am wanting to look at the console. If I set fullscreen=true, the blue background still turns red.

Windows 7 RC1 32-bit
AMD Turion X2 Mobile 2GHz
3GB Ram
Radeon X1200

To Reproduce:
Open DosBox 0.73 in windowed mode. Hit Alt-Enter. The blue should invert to red.

    Forgot to mention that I am using the default output, surface. The other ones do not do this, but they do not have scaling, so they do not fit the screen size.

    Hi, I had exactly the same problem and it made some games (ie Albion) unplayable in fullscreen. I tried several changes in config file (dosbox.conf) and this seemed to fix it:

    scaler=supereagle forced

    Try it and pls let me know if it fixed the problem for you too.

    this should have been fixed in 0.74.
