Created attachment 275605 [details] testcase My brother saw annoying white stripes while scrolling through his mail messages (especially with images he told me). I checked this and I could reproduce this on branch, but not on trunk. The attached testcase is not minimized yet. I'll try to minimze this further.
On trunk this was fixed between 2006-01-25 and 2006-01-26, so fixed by the frame display lists patch, bug 317375.
I guess this should become wontfix?
Marking resolved worksforme, as this is only a problem in the 1.8 branch and not in later builds and the 1.8 branch is not maintained anymore by Mozilla.
