The wrong contents aren't Win7-only, anyway.

Comment 2

[:Margaret Leibovic]

I'm seeing a problem with the tab tooltips being wrong and/or cut off on OSX, and it sounds like it might have the same root cause.

[Toshihiro Yamada]

It seems that this problem reappeared since m-i changeset 6b58397ad735(landing of Bug 539356)

Also, possibly related symptoms: With the Stylish addon, clicking the Status Bar icon will display a menu with the styles that apply to the page you are viewing. Those styles do not show until you move the mouse over the line where the style(s) would be listed.

Also, applied styles may not work, i.e., web page not properly repaint, as expected.

[Justin Dolske [:Dolske]]

I'm not seeing the black glitch with this DLBI landing, but do see wrong contents and/or wrong size. I verified that FillInHTMLTooltip() is working as expected, too.

I can reproduce this by loading twitter.com/dolske, and just moving the pointer back and forth between a couple of URL links (which trigger tooltips). After doing this a few (random?) times, the tooltip gets stuck on one value and no longer changes.

I tried to find a way to reproduce this problem before http://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/mozilla-central-win32/1348986078/firefox-18.0a1.en-US.win32.zip , but the UI has changed so much that I can't.

I'm 99.99% sure this was fixed by bug 795576, please reopen if you can still reproduce.
