--- Comment #3 from Daniel van Vugt vanvugt@gmail.com 2008-02-09 10:50:21 --- Suggestion: Perhaps change the Summary of this bug to "Wine probes xrandr too many times, and repeatedly in some apps, causing screen flashing with some X11 drivers"
I think this is more reasonable. It's not uncommon for a video output to flash once when probed. It's just a little too much if that probe is triggered repeatedly (as wine does).
