[Qemu-discuss] -accel hax works only in Window not in full screen

[Peter Fodrek ml]

Dear Qemu experts,

We need to run DOS based CAD/CAM program via disk image as system in Windows7
or more recent

I works but it is too slow for large CAM -NC programs therefore we tried to
use HAX via HAXM as speedup technology It works, when DOS is running
inside Window but does not change screen when used in fullscreen mode

Is anyone able to get us reccomentaion what to do, please?

I look forward hearing from you

Yours faithfully

That's weird. The HAX support should be entirely orthogonal to whether
the display is being viewed fullscreen or not. (I guess it's possible
that we're not getting the "hax needs to tell us about dirty memory
regions in the display memory so we can update" part right.)

thanks

Thank you.. I seems graphics is only problem when using HAX and quemeu for
us.

We would like to be informed about your patches, please

I look forward hearing form you
