Red Hat Bugzilla – Bug 1029835
Expanding a thread leads to redraw errors
Last modified: 2014-02-11 09:06:06 EST
Description of problem:
When expanding a thread, the redraw of the folder goes awry - blank lines appear and odd fill/draw errors occur. Selecting a message makes that one draw ok; scrolling the window seems to fix it. Unfortunately, print-screen does not capture it, instead seeming to trigger a redraw - I'll attach a photo of the screen.
Doesn't seem to happen in other apps.
Version-Release number of selected component (if applicable):
adapter is "r600"
Not sure what else is needed for a draw/graphics bug - please let me know.
Steps to Reproduce:
1. Open thunderbird
2. Expand a thread
3. Observe draw failures
Drawing is ok
Didn't happen in thunderbird 17
Erm... blast. I just accidentally closed thunderbird, and when restarted it, it's no longer showing that behaviour.
However, I know I've restarted it before and it has; I'll work for a day and try to reproduce, but if I can't I'll close the bug - suggest ignoring for the meantime, sorry for the noise :o(
Ok, I've reproduced a similar drawing bug - this one takes place when:
1. Select a range of messages
2. Then try to select a single message inside the range
...and messages "below" the one you try and select but inside the range have drawing errors, as per the attached message

As noted, print-screen doesn't capture them - seems to trigger a screen-wide redraw?
In case it helps, this problem seems to get worse the longer the process is running; it eventually gets to be unusable, but a restart returns it to reasonable health for a while.
Same problem here. Merely making the mouse exit the window seems to redraw the expanded tree as well (I have focus-follows-mouse enabled) so it must be redrawing on focus change at the least.
Yes, I can reproduce it too, on Radeon HD 4770 with kernel driver. Works fine with Intel.
I'm using Nouveau here.
Add me to the list on F18. Also on a system with Radeon HD 4200 using stock radeon drivers.
FWIW, since CentOS 6.5 updated to thunderbird 24 I am seeing the same thing there, could be an upstream bug?
After more digging upstream, I found these two bugs which appear to be related:
And this bug on F19:
No help or solutions on any of them, though.
This message is a reminder that Fedora 18 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 18. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '18'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 18's end of life.
Thank you for reporting this issue and we are sorry that we may not be
able to fix it before Fedora 18 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior to Fedora 18's end of life.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Reproduced on 19

Let's track is upstream.
