Blue MSX - full screen mode

Sounds like a bug in your graphics drivers... try to upgrade them to the latest version.

Did this issue just suddenly occur?
Did you change something to, or install something on your system recently that could have an effect?
Do you use v2.8.2 (not a more recent beta)?
Tried with a fresh/clean 'install' (just unzip the zip-package)?
Is your fs resolution setting compatible with your setup (and set to 32 bit, not 16 bit)?

And.. do you have the same issue with similar apps (emu's)?

That's one way..

My full screen goes crazy on Windows 10. Shows only a part of the screen in any resolution
