Interestingly this happens even when the ITV website is not the current/active tab when using tabbed browsing. Reproducible: Always Steps to Reproduce: 1. Vist http://www.itv-f1.com/. 2. Wait till the news ticker has loaded. 3. Try a few of the pull-down menus. You may need to open a few menus before its starts to exhibt the problem. Actual Results: The menus are displayed and usable, but the edges / drop-shadow flickers. Expected Results: Display menus without flickering. Relevant part of the code: <td colspan="3" height="" class="blackborder"><applet codebase="/js" code=aTicker.class width=524 height=20> <param name=file value="s"> <param name=cSep value=";"> <param name="speed" value="1"> <param name="delay" value="30"> <param name="delay2" value="3000"> <param name="local" value="true"> <param name="bgcolor" value="13311"> <param name="s0" value="*** Don't miss the F1 Pre-season Show *** ; http://wwww.itv-f1.com/ ; "> <param name="s1" value="*** This Sunday 14.30 – 15.30 on ITV1 *** ; http://wwww.itv-f1.com/ ;"> <param name="s2" value="*** including the studio debate... *** ; http://wwww.itv-f1.com/ ; "> </applet></td>

perhaps another test case : www.bel1649.nl causes my entire screen to flicker (xp pro sp1, 32MB tnt2 ultra with 4x.xx drivers from Nvidia, JRE 1.4.01)

Hmm.. I am unable to repeat this bug in: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3b) Gecko/20030210 Do you get the same problem in full mozilla?

Another test case: http://news.bbc.co.uk has a scrolling Java ticker, and also causes the menu to flash. Actually, it has always flashed in Mozilla releases in recent memory (1.0 onwards).

An update: updating my JRE installation to 1.4.1_02 made the menu flash disappear. The submitter may want to try this. (Oh, yeah, my platform: WinXP SP1; and now JDK/JRE 1.4.1_02, and Moz 1.3b).

Updated to JRE 1.4.1_02 -- seems to have fixed this issue. Cheers.
