2D fullscreen apps display corruption

If I run 2D apps (like pinball, or some educational games for my kids) in fullscreen mode:

1. the app will appear fine until I switch back to normal windows, then display is corrupted. for instance pressing F4 to switch to fullscreen in pinball then pressing it again to swtich back to windowed mode.
OR
2. the display is corrupted straight away.

the display is cross-crossed like blue/black tartan!!

The only way to rectify this is to close the lid, go into sleep mode and open the lid again and press space bar to wake it up again and all is fine again.

I've tried ATI drivers (modded with dh_mod), Omega drivers no effect. Is this a lcd issue rather than vga drivers? I've tried switching to "no acceleration" in the vga drivers. this had no effect either. I've tried updating Directx too with the oct 2006 redist package.

BTW, 3D apps like Half-life2 DeathMatch run fine.

any ideas?

many thanks in advance.

specs:

Acer Aspire 5024WLMi
ATI x700 mobility 128MB (currently latest omega driver)
512MB RAM
Windows XP Home spk2
directx 9.0c (Oct '06).

 

First off thank you for being very specific in what you have tried so far to fix the problem.

If you asked me what the problem is I would have to say that it is due to the wide screen format of your laptop (16:10) vs. running a 2D application in 4:3. The only suggestion I have is to run it in windowed mode and instead run it @ full screen.

Personally I have yet to have problems with 2D applications, but then again anything is possible.

It almost sounds like windows is holding onto the 2D interface @ full screen once you bump out of the game! Try running the game in Win2K compatibility mode if it was designed for Win2K. Right click the .exe and select 2K etc.

Good luck,

thanks, I will give the compatibility mode(s) a go.

 

I gave up trying to tweak it back into full health.

Problem resolved by restoring the original install from Acer CDs. that'll teach me not to meddle with GFX drivers.
