--- Comment #18 from Viktor Mileikovskyi v_mil@ukr.net 2012-09-22 12:55:11 CDT --- The same problem is for DraftSight. The drawing area appears gray when 1. Mouse moved away from drawing. The drawing reappears when mouse returns to drawing 2. Any command performs. The drawing reappears when execution of command is finished. The result is a quick blink. 3. Any dialogue appears. The drawing reappears when dialogue closes. This blinking may cause eyes to be tired and after continious work it may cause injury of eyes.
