375967 - header and account-explorer pane are not redrawn after maximizing the app window

Status: RESOLVED WORKSFORME

(Thunderbird :: Mail Window Front End, defect)

Description

[Peter Möller]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; de; rv:1.8.1.2) Gecko/20070221 SUSE/2.0.0.2-8.2 Firefox/2.0.0.2
Build Identifier:  2.0pre (20070312)

its an ugly bug for me, the reporter, and for you, the developer, because i can't figure out, which of the many possible circumstances make this bug happen :-(. I try:

first some constraints:
- I did not see the effect, when the appl windows is small, that is why i suggest you to use maximize
- since i suppose a similar redraw architecture in firefox, let me mention, that i can't see this with firefox V2.0.0.2 ever
- no other appl shows this behaviour
- my grafic card is an elder ATI Radeon (RV350 AP) with fglrx driver and 3d activated
- my xserver is xgl as delivered with opensuse 10.2 (including updates)
- one click inside the appl area will force the missing redraw

for better understanding i will add a snapshot, showing the worst case, where there is not even the message pane refilled.


Reproducible: Sometimes

Steps to Reproduce:
1. Minimize the appl window
2. Maximize the appl. window
3. The header pane of the app and the account explorer pane (typical on the left side) will not be redrawn
Actual Results:  
the window region of this panes just shows the background behind the appl window. Also the border line of the appl. is missing
Just sometimes also the message pane has no redraw

Expected Results:  
a correct redraw of the appl panes

some note on "Reproducible: Sometimes" i can see this in 4 of 5 cases ;-)

Comment 3

[David :Bienvenu]

have you tried running in safe mode, without any extensions enabled?

Comment 4

[Peter Möller]

good advice David, because I hesitated to switch off xgl again ;-). And we have some result:

- using safe mode i cannot see the effects at all. Seems to be a problem with xgl maybe

On the other hand i must admit, that meanwhile i have also seen this effect with firefox and konqueror (using xgl). I'm not sure anymore, whether there is a  problem with my graphics card too. I will compare it with a win2000 os, where there are a few games, using 3D.

Reporter, does the issue still occur in the latest supported 2.0.0.x / Shredder trunk nightlies?

(1.5.0.x is end-of-life and the latest supported 2.0.0.x is 2.0.0.17)

I can't reproduce the bug anymore, maybe due to a change of my hardware. Have an ati 4850 now and no more problems. In fact, i think, that it was a bug of my last ati card or its driver - more then in thunderbird sw.
-> please close it
