Running SW16SP3.0 on Win-7. I'm noticing only lately an irritating screen flick. Not consistently but then sometimes often. If I do normal things like rotate or zoom, it flows normal, but like on the very last step near resting point, it does a high speed 'flick' like a mini image refresh. I checked this forum post noted below, perhaps not 100% related. Anyway I checked Windows updates & don't have KB3205394 installed. In fact I haven't made Win updates since before this seems to be occurring. I've fiddled with backgrounds & different vintage files, same result. Ran SW RX & everything ok. My video card is driver is current/recommended. Any ideas?
