S!
I experienced the blue flashing etc with 9.11's the text is garbled and so forth. For me the text clears when flying, as offline you only get to this "garble mode" when game starts to load environment etc. Joining online games is impossible as the environment is loaded before the briefing thus you can not see your mouse or icons or anything..and you need to get into game to get rid of the blocky text.
I fiddled with my conf.ini and got away with ALL the artifacts in graphics EXCEPT the blocky text. Take a look, makes you think what the game REALLY needs to look good and run
I am under OGL mode with ATI 5870..Win7 etc.
