306466 - very slow redrawing after some minutes in minimized-state

Status: RESOLVED DUPLICATE of bug 299578

(Thunderbird :: Mail Window Front End, defect)

Description

If I minimize thunderbird (or firefox), wait some minutes and maximize it again,
it takes up to 15 seconds until I can use thunderbird again.
TB redraws one after another element (listboxes, menues, texts) very slow... 

Some time ago, I programmed a smal program in Borland Delphi. There, I wrote a
lot of entries into a listbox. I saw, that it takes a very long time to write
all these entries. I modified the code: At first, I disabled that listbox, then
I wrote the entries into it and then I enabled it again. This made is much much
faster.

Back to TB: It could be possible, that the problem with slow redrawing can be
solved by hiding (or disabling)at first all elements in TB, then redrawing them
and after that they should be made visible.

I hope, someone understands my, because my English is very bad :(

Reproducible: Always

Andreas,
Please provide Hardware Configuration Info.  CPU, CPU speed, RAM, Graphic card
make/model, etc.  Also, were you running some other large programs while
Thunderbird was minimized?

this can be slow, but I've always thought it was because of virtual memory, and
that a lot of the memory we're using had been swapped to disk, and slowly paged
back into memory.

1000 mhz Duron (same problem on 2000+ AMD athlon mobile and 1600+ Amd desktop)
256 MB SDRAM
elitegroup K7s5a Mainboard, newest firmware
Pixelview Geforce 2 mx400 (I've tried various drivers, but all the same problem!)
no other large programs are running. only winamp, thunderbird and firefox.

need further information?

I just looked into my taskmanager: TB uses about 22 Mbytes of virtual memory all
time. It uses about 2 Mbytes RAM in minimized-state and about 10 mbytes in
maximized-state.
It's strange: Sometimes when I restore TB-window it is fast, sometimes very slow. 
Although memory-usage is the same.
