274521 - CSS (border) on FRAMESET causes smudge when scrolling

Status: RESOLVED FIXED

(Core :: Web Painting, defect)

Description

[nrlz]

If I use this style rule:

<style>
frameset {border: 1px solid blue}
</style>

And then *scroll* the frame, the styled border (blue line) gets drawn over the
webpage repeatedly. See the attachment for exact meaning.

The frames should be scrolled both up and down for maximum effect.

I can see the bug, using:
Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8a6) Gecko/20041213
Firefox/1.0+
This looks similar to bug 269840.

I see this...

Given that we don't really support CSS borders on frameset/frame, should we
perhaps just disable them?

I can see the bug on branch, but not on trunk.

<iframe> would be a different bug.  Please file a separate bug for it.
