Ok, I flashed CM7 about a week or so ago and I'm loving it. One quirk I noticed, however, is that from time to time the screen will go black. For example, I will open up GoSMS and it will just be a black screen. The screen will still function and be responsive to touch (you can type, or select threads, etc), but it is totally black. This happens with mail programs, dialers, etc. so it isn't app specific. There doesn't seem to be any rhyme or reason to it, has anyone else experienced this?
