Graphic glitches

[spillblood]

Here's some screenshots that show the graphical glitches in combat. The glitch on the map happened when I tabbed in and out. Please fix that stuff or give me some advice what to do to fix that. I have no real combat effects, just glitches. Note the lines and dots in tactical combat screens. They seem to replace the combat graphics and expand or move randomly across the screen. Very strange.
