There should be a .RPT file with more information.

Things to try: • Upgrading graphics drivers • Playing with graphics driver settings, turning off compositing.

In https://github.com/Warzone2100/warzone2100/commit/049e9edaaa1a8fe6e4a9cfe8ba97987a9c3d1bbc:

#CommitTicketReference repository="" revision="049e9edaaa1a8fe6e4a9cfe8ba97987a9c3d1bbc"
gfx: Don't use fixed pipeline for alpha test.

Also, don't read back from gl_FragColor.

Thanks to vlj for debugging.

Probably fixes #4455 and #4462. May or may not fix any other driver crashes.
