On Windows 2000 machines set to use outline dragging, resizing the Extensions
dialog using the bottom-right ridged "sizer" causes solid-dragging. This bug can
also be seen in the Themes and Downloads dialog.

Reproducible: Always
Steps to Reproduce:
1. On your Windows desktop, choose Start|Settings|Control Panel.
2. Open the Display applet and choose the Effects tab.
3. Make sure "Show window contents while dragging" is _unchecked_.
4. Open Firefox and choose Tools|Extensions.
5. Move your mouse over to the ridged "sizer" in the Bottom Right
   corner so that your cursor turns into a doubleheaded NW/SE cursor.
6. Make sure your cursor is nearly in the middle of the sizer, as shown
7. Click and drag the window around (to resize it).

Actual Results:  
Window contents are shown while the dialog is being resized. (This is also
called "solid dragging".)

Expected Results:  
The window contents should _not_ have been shown while being resized (a.k.a
"outline dragging").

Note that for the following positions _near_ the sizer, solid dragging does
_not_ occur:

This bug would be a minor one but it is exacerbated by the fact that painting
the Extensions (and Downloads, and Themes) dialog seems to be a very slow
affair, especially on machines with mediocre video cards. On my old Thinkpad T20
with an S3/Savage IX (8MB video RAM), the system stutters while painting these
dialogs during a resize or scroll. Someone may wish to investigate this as a
separate bug.

I have also noticed this behavior in the main browser window.  If you resize by
grabbing the very edge of the window the resize pays attention to the system
setting.  If you grab the resizer, as noted in the first comment, the window
contents are shown while resizing the window.

Does it still ignore it in Firefox 1.0?
Severity: normal → minor
Component: General → Extension/Theme Manager

Screenshot of where Firefox 1.0 still solid-drags

In firefox 1.0,
is fixed, it honors the outline drag pref now.

However there is stil a case where it solid-drags, I've created an attachment
that shows where.

Confirmed on WinXP, Firefox 1.0

1. My computer -> properties -> advanced -> performance -> settings -> custom ->
uncheck "show window contents while dragging".
2. Tools -> Themes or Tools -> Extensions
3. Drag the grippie (not the border itself!) in the down-right corner (as on
screenshot). The window content will be redrawn, some visual artifacts may be

similar action works correctly with native win32 applications, like foobar2000
Ever confirmed: true
OS: Windows 2000 → Windows XP
Summary: Resizing using Sizer in Extensions dialog ignores system settings, always shows window contents while dragging → Resizing Extensions dialog shows window contents while dragging (ignores system settings)
