Tactics ogre : Let us cling together

[bliggles]

i have no huge issues with v0.9.9.1 on windows 8.1, but theres a nuisance im facing, i wish i could catch a screenshot of it but it always goes away when i attempt to do it. My problem is the game spazzes out no sound problem only a little static sound here and there but the letters and graphics spazz out after a little while lets say 3-4 seconds it comes back to normal anyone else have this issue. Any help and private message pertaining the issue is appreciated ty.
