102062 - Popup menus redraw everything when scrolling

Status: NEW

(Core :: XUL, defect)

Description

[Pierre Saslawsky]

Tested with a carbon build on MacOS 9:
- Set user_pref("nglayout.debug.paint_flashing", true);
- Recompile the View Manager without double-buffering
- Launch the app and go to the font prefs panel
- Open the Serif popup menu and start scrolling by positioning the mouse over the 
arrow at the bottom of the popup menu
===> The entire menu is redrawn everytime we scroll one line

In fact, we should scroll the (n-1) lines at the top and repaint only the last 
line.

This has to do with the disabling of bit blitting on any internal scrolling views.

This bug is targeted at a Mac classic platform/OS, which is no longer supported
by mozilla.org. Please re-target it to another platform/OS if this bug applies
there as well or resolve this bug.

I will resolve this bug as WONTFIX in four weeks if no action has been taken.
To filter this and similar messages out, please filter for "mac_cla_reorg".

This bug hasen't been touched for years and is clearly unowned. Moving back to default assignee/QA so that people, who are watching those can accurately triage this bug.

Also resetting Priority, Target Milestone, Status Whiteboard and Status.

Hard to tell with paint flashing not working at the moment (bug 334411).

I think the bug described by the reporter no longer exists. But setting nglayout.debug.paint_flashing to true instantly causes Firefox to take an acid trip.
