Bug ID: 368880
   Summary: Crash when multiple documents are open and one of the
tabs is closed
   Product: krita
   Version: 3.0.1
  Platform: MS Windows
OS: MS Windows
Status: UNCONFIRMED
  Severity: crash
  Priority: NOR
 Component: general
  Assignee: krita-bugs-n...@kde.org
  Reporter: jarodragon@gmail.com

Hi I've had this issue occur during 3.0 Krita and I was hoping it was a bug
only for that version, but it's been a consistent issue with 3.0.1 after
installing it. I do not know if this is a problem within my setup, but here's
what's happening:

I have more than one Krita document open, which can be navigated between, but
attempting to close either one or the other tab (without closing Krita
entirely) produces an immediate crash. This happens regardless how many tabs
are open (exception: only one document is open).

I have a multi-boot computer and I haven't tried Krita 3.0.1 on my older
Windows 8 boot, but I may attempt it to see if it's consistent there too.

This is the first time I've sent through a bug report so please let me know if
I should provide more details! I'm also getting mixed messages on what program
to use to provide a back-trace, what would be the best option?

P.S This is probably a seperate bug which I'll report in a new thread, but I
think it relates to the above problem: I also can't edit anything in the first
tab(s) (can't zoom, can't pan, brush marks don't appear, even though layers
show change), while the latest tab (most recently opened file) is still
functional.

Reproducible: Always

Steps to Reproduce:
1. Open two (or more) documents
2. Close one of the tabs

Actual Results:  
Windows shows the 'Krita has stopped working' dialogue box, then closes the
program.

Expected Results:  
The selected tab closes, while leaving the other open and editable.

Other specs:
Windows 8.1 64 bit
Wacom Bamboo tablet
Switchable graphics: in-built Intel HD Graphics 4000 and switchable AMD Radeon
HD 8730M

Update: I switched off OpenGL and I had no issues with closing tabs. However,
I'd rather not work without OpenGL, since it gives performance boosts.
Should I move this bug report into OpenGL Component area?

Hello!
Sorry for the slow reply, I had to go through a number of projects.

I feel a little bit of a doofus right now. I decided to try downloading an
update for my Radeon graphics card, since I was having blue screen issues with
'Watchdog' in general too. Turns out that by updating my graphics card, the
multiple windows no longer crash.

For the time being, I guess that means the issue is solved. If I do notice that
I can reproduce the issue again in some form, I'll give an update.

Thanks for the help anyway, Boudewijn!
