Comment 1 David Edmundson 2015-10-28 14:44:05 UTC

sorry we didn't do anything with this, there's not a lot to go on and I've not seen any other instances of this.

Anything in thread 8 is typically deep in either: 
 - one of the JS interpreters which is super deep in QT
 - your graphic driver if we have threaded window rendering

so hopefully this is solved by some library updates.

5.3.2 is rather old now, do you still have this problem? Please reopen if it does and we'll try and get some more info.
