Status: VERIFIED FIXED

(Core Graveyard :: GFX, defect)

Description

[Steve England [:stevee]]

Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9a1) Gecko/20060309 Firefox/1.6a1 (places, non-cairo)

1. New profile, start firefox
2. Make a bookmark for about:config
3. Middle click this bookmark so it opens in a new tab (in background)
4. Change to tab

Observe the top of the window is not drawn correctly; it 'leaks' what was in the same place on the previous tab.

Backing out the windows patch for bug 328337 seems to fix this.

I've filed bug 329944 for the scrollbar components. It seems that the painting bug is more easily reproducible when several tabs are being loaded and when we switch from 1 tab to another. Then, the re-drawing, painting is not best, not refreshed.

Checked in a fix making the entire patch for 328337 MOZ_CAIRO_GFX-only; I'm guessing what we really want is the MOZ_CAIRO_GFX case in both places even with non-cairo, but this is safer for now.
