416129 - table renders in incorrect location, okay after window focus changes

Status: RESOLVED DUPLICATE of bug 416073

(Core :: Layout: Tables, defect)

Description

[[e-mail] (:bhearsum)]

Attachment: table in incorrect location

I can't make this happen on all tables but I've attached a screenshot. It fixes itself after I change to another Firefox window or other application. Scrolling, tabbing, etc. does not fix it.

Probably a dupe of bug 416073. Can you reproduce this consistently?

Comment 2

[[e-mail] (:bhearsum)]

Yep, reproducable 100% of the time.

Ben, what's the web page that shows this problem?  Having that would really help with debugging this and all...

It's on mpt-vpn, so you probably can't access it :(. I've just seen it happen on the Firefox tinderbox, though.

bz - I can reproduce this 100% of the time if I load tinderbox (since it's a giant table with many reflows) and pan around while it's rendering.  On fast internet, you might want to load tinderbox with something like &hours=200 to introduce more lag.

Just to be clear, I can also confirm that changing focus to, e.g., the error console will repaint everything properly (even sections that are not hidden and which I wouldn't have expected to be invalidated).

Tinderbox is bug 416073.  I guess I'll fix that, and then you'll see whether that fixes this bug.

Jonathan, we invalidate the world on focus changes.  It's pretty silly, and a performance nightmare...
