Possible solution: Add -J-Dsun.java2d.noddraw=true to startup JVM arguments.
We did try to run Nb8.2 out-of-the-box on the Alienware and it did not show the flickering/window-dropping as with the RCP app. Checking the netbeans.conf we did see the -J-Dsun.java2d.noddraw=true which the RCP did not have. Googling the argument did show it had some connection to Windows/graphic-cards/Swing. Adding -J-Dsun.java2d.noddraw=true to the JVM args of for RCP did for now over 48 hrs keep it from doing the wicket flickering .... We have taken it out of the netbeans.conf to see if Nb starts going ballistic (which would be the proof of the pudding) but that has not happened yet. We will see maybe this is a red Herring .... Just wanted to keep you updated .... thanx for the interest in this question. Really appreciate the feedback given.
