48863 - Text overwrites dragging in History

Status: VERIFIED DUPLICATE of bug 49094

(Core :: XUL, defect, P3)

Description

[Randell Jesup [:jesup] (needinfo me)]

I selected (via menus) Tasks/Tools/History.  When I click on the slider button
and drag, I get serious draw problems, including large undrawn areas and areas
that are overwritten.  See the GIF I'm attaching.  Side note, to be entered as a
separate bug: after I click on the slider button, it doesn't notice the
up-click, and instead follows the mouse until I click again.  Also a separate
but perhaps related bug: very bad performance when dragging.

Various misbehaviour is later described in bug 49094 "scrollbar thumb is
dragable". But noteworthy: Scrolling with mousewheel does NOT show the
mispainting. I do, h owever, see the same as you on linux 2000081509 when
scrolling by dragging thumb/slider. I think this all boils down to the slider
button bug.

49094 is already set to OS and Platform: ALL

Adding comment there about this bug, i think it can be marked dup (even if you
probably were "first poster"..)

Yes. I disabled D&D for the history.xul, and could no longer reproduce this 
behaviour. There are open bugs addressing tree-scrolling perf, which is the 
other part of why this is happening. Marking this bug a dup of 49094. Thanks.
