From Bugzilla Helper: User-Agent: Mozilla/5.0 (Macintosh; U; PPC; en-US; rv:0.9.3+) Gecko/20010807 BuildID: 2001080708 When you use one of the buttons on the bottom right side, up or down it causes the screen to flicker, i was only able to reproduce this on a MAC it works perfectly on windows 2k and 98se. It seems that the flash element (flash 5 plugin r41) on the top right corner in combination with javascript is causing the problem here. Reproducible: Always Steps to Reproduce: 1. go to the URL mentioned above (http://www.lithopartners.nl/site2001/print.htm 2. just move your mouse over one of the 2 "hooks" in the bottom right corner of the page (they are GIF's wich function as up and down scroll buttons) 3. let the text scroll some, try both buttons Actual Results: The screen starts to flicker and the scrolling is slow (but that could be an other bug) Expected Results: The text should scroll without causing the whole screen to flicker If you remove the flash element, all is fine the screen stops to flicker. i have reproduced this on several MAC's available at my disposal 1st. configuration: Dual G4 450 Mhz, 640 MB 100 Mhz Memory, ATI rage pro 16 MB videocard. (Mozilla 0.9.3 2001080708) 2nd. configuration: G3 400 Mhz, 512 MB 100 Mhz Memory, ATI Rage Pro 16 MB videocard. (Mozilla 0.9.3 2001080708) 3rd. configuration: G4 466 Mhz, 384 MB 133 Mhz Memory, ATI Rage Pro 16 MB videocard. (Mozilla 0.9.3 2001080708) all with the same result.

I think this is a duplicate of bug 44298. Reporter, please test the testcases on that bug and see if the same problem occurs for you. For what it's worth, I don't see this problem using Mac Mozilla 2001080214 (0.9.3). I do, however, see the scrollbar elevator flash during drag when the displayed page contains a Shockwave Flash element.

No i'm pretty sure that it's no duplicate, the bug you are refering to is caused by an "overflow" attribute on the DIV, in my example there is no overflow, just a clipped layer, controlled by javascript. As i stated earlier, the combination of flash and scrolling (javascript, DHTML whatever you wanna call it) seems to cause the screen to flicker, if you remove the flash movie from the page, the scrolling goes smooth without any signs of the problem mentioned before.

Sounds very much like a dup of bug 62891. Please re-open and assign to me if not. This is caused because double buffering is off on any page that uses a plugin, only on Mac. You can try to manually override and turn it on by setting this pref but some plugins may have serious problems: pref("plugin.enable_double_buffer","true"); *** This bug has been marked as a duplicate of 62891 ***

Indeed guys! that's the one, my excuses for not searching that well.

SPAM. HTML Element component deprecated, changing component to Layout. See bug 88132 for details.
