Description Vladimir Benes 2010-06-18 11:50:08 UTC
Description of problem:
I see rendering issues while scrolling if the ffox window is moved a bit down from it's original position. The problem can be seen only if the bottom edge is moved below visible area otherwise it behaves well.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.grab Firefox window and move it down to hide its bottom edge under visible area
2.scroll up and down
Actual results:
rendering issues

Expected results:
seamless rendering

Additional info:
you have to scroll by the touchpad's scroll area (grabbing scroll bar doesn't break things)

And a screenshot please.  "Rendering issue" is rather vague...

scrolling issue

Sorry for bad quality (taken from mobile phone). I wasn't able to use any screenshot tool, as it causes refresh of the screen, and the issue is not so easy to reproduce :-D

Hello Issue is not that easy to reproduce, but it's still here (see attached screenshot).

Useful detail:

if you'll click by mouse outside of firefox, these defects will disappear.

Comment 18 Matěj Cepl 2010-06-24 15:47:22 UTC
And yes, I can reproduce this even with other applications ... eclipse for example and scrolling with the list of bugs in Mylyn up and down.

This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release. It has
been denied for the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current

your behalf. Otherwise ask that it be considered for the next
