Vassal Glitching on Menu/Tab Opening

I have Vassal latest version loaded on both my laptop and desktop.

Desktop Alienware AMD Ryzen 7 3700x 32.0 GB
Laptop Intel i5-9300H 8.0 GB

On the Desktop - vassal glitches and screen starts splitting into multiple displays when I do menu tabs or counters that have extra actions. Have to close program and reload to fix glitch. Is there something that I need to set or fix - I have latest Java loaded on both but for some reason Desktop version glitchs almost 75% of the time. No issues with Laptop - same Vassal module version and java.

You didn’t mention what OS you’re using.

  • For Windows: Troubleshooting Common Problems - Vassal

  • For MacOS: If you’re using an M1 Mac you’ll find a Preference labeled “Disable OpenGL FBOs” in 3.6.0-beta1 or later. You’ll want to tick that.

If neither of those apply, we need more information about your system.

Here is a screen shot – the map has glitched into 3 copies of the map overlapping each other

Windows 10 21H1 Home Version

In that case, the Windows link above has your solution.

Seems to have done the trick. Thanks for the quick help – this glitch has been driving me crazy!
