Details

NOTE: I have found a number of bugs in Bugzilla that seem to refer to this bug, but state "Works for me" or "Duplicate Fixed". However, this is completely reproducible in 1.0RC1. 1. Go to the listed URL. 2. Note there are two GIF images on this page, one is the printed word "Rajika Puri" in the upper left corner, and one is the photo (woman with black hair) in the upper left of the white (non-menu bar) section of the page. 3. Scroll down, could be by pressing down arrow key six or seven times. 4. Scroll back up, could be by pressing up arrow key six or seven times. 5. The text "Rajika Puri" in upper left is still rendered perfectly, however the GIF photo is ballocksed up.

Still happens for me, also see top left image in http://www.pfile.com/ . It seems to me this has something to do with GIF images that have transparency in them. So far I have seen such GIF images get messed up, and no others. BTW, the screen does redraw properly if you press the REDRAW button, or if you bring another window to the top and then bring the browser window back to the top.
I have found a new wrinkle to this bug... It does NOT happen if JAVA is up and running. So, if JAVA is used from somewhere, and THEN I go to one of these pages where the transparency around a GIF gets mucked up by scrolling, there is no problem. But if I exit and restart Mozilla and go to such a page (like the referenced one above, http://www.rajikapuri.com/bio.html) and scroll the GIF on and off, the poor redraw behavior is as described in the original bug.
Possible dup of bug 96803, where another user reports random distortion when scrolling a gif with transparency.
I can't reproduce this problem in the July 16 build (2002-07-16-08 1.0.0) under Windows ME.
