820732 - Xull tree render issues in FireFox for OS X

Status: RESOLVED INCOMPLETE

(Core :: XUL, defect)

Description

[Martin]

Attachment: redrawtree.xul

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_8) AppleWebKit/534.57.2 (KHTML, like Gecko) Version/5.1.7 Safari/534.57.2

Steps to reproduce:

Create a FireFox Extension with a Tree and a Checkbox


Actual results:

In FireFox 14 and up, on OS X, the tree experiences redraw issues. When hovering with the mouse over the treerows, they randomly disappear and reappear.

Setting the checkbox to "display:none" the issue disappears.

Removing the global skin directive in the example xul file also solves the problem ( but of course the styling is then not horrible to the eye).


Expected results:

Mousing over the tree rows should not disappear.

Noticed that specifying a specific height 'style="height:16px"' to the checkbox works as a workaround

If it worked normally in FF13-, could you use mozregression (see http://mozilla.github.com/mozregression/ ) to find a regression range please?

The first Firefox 14 nightlies start in March (--good=2012-03-10).

i was busy this week but I can now bisect it.
anywaym, I can see the issue in Firefox18 on OSX.

I can't bisect because my build on OSX10.8 crashes on startup :-(

bug 733607 looks suspicious to me as amateur
