Description Paul Johnson 2015-01-05 08:26:29 UTC
When editing Android UI layouts, I am able to edit one or two files then XS locks up giving the spinner on the UI layout designer (the source can be see, but not the design). If I close the designer, I am still able to use XS but it is considerably slower.

Usually to resolve this, I either have to close the project and reload (though this will only allow me to edit one file at most) or quit XS and start again.

The log produced shows a cairo memory leak

Comment 1 Atin 2015-01-06 11:36:33 UTC
I have checked this issue and, also observing the same behavior/output in Ide logs. To reproduce this issue I have followed the instruction provided in bug description.

Steps I followed:

1. Create a Android Application in XS.
2. Add two or more Layout Designer files in Layout folder.
3. Drag some "Spinner" control from toolbox on the designer files.
4. Drag some other controls, perform some action like edit, delete  and save.
5. Open Ide logs and observed the logs produced.
"Cairo.Pattern is leaking, programmer is missing a call to Dispose.

Screencast: http://www.screencast.com/t/n8XZGIv2lC

I am observing the same logs at my end, but my XS not getting hang. Could you please let confirmed that Is this the same issue/behavior experiencing by you ? If no then, please let me know that what steps I am missing or should I follow to reproduce this issue?

Please let me know if I am missing anything ?

Comment 2 Paul Johnson 2015-01-06 12:23:53 UTC
The hang seems to occur when you have a large project loaded. It doesn't seem to make much difference the number of source tabs that are open, just the number of designer files open.
Comment 3 Paul Johnson 2015-01-06 12:25:06 UTC
I've also observed this happening when working on Xam.Forms applications too (in the PCL part)
Comment 4 Jérémie Laval 2015-01-13 09:08:09 UTC
Hi Paul,

The memory leak messages from Cairo are normal in those cases, the problem is elsewhere (like this container removal error in Gtk+).

When XS hangs next time for you, can you wait a bit and then open a terminal and execute the command `kill -QUIT <PID of Xamarin Studio' then attach on this bug report the content of your Xamarin Studio log directory (~/Library/Logs/XamarinStudio...)

Thanks
Comment 5 Paul Johnson 2015-01-13 12:10:31 UTC
Created attachment 9341 [details]
XS log file

I was unable to use a normal kill -QUIT PID for this, so had to use kill -9 PID instead
Comment 6 Jérémie Laval 2015-01-16 09:34:53 UTC
From the look of the stacktrace dump it looks like a deadlock in the debugger. Re-assigning.
Comment 7 David Karlaš 2015-01-18 03:29:37 UTC
Hi Paul,

does this happen during debugging/at end of debugging(e.g. when debugged application crashes)?
Comment 8 David Karlaš 2015-04-30 08:51:48 UTC
This is fixed in XS 5.9, this was bug in debugger that deadlocked UI thread.
