not sure but looks as if refreshKeys was called zillion times, maybe fixed in core-main #b9d585b24a9b ?

Comment 3 Theofanis Oikonomou 2014-03-03 10:41:01 UTC

This is caused because the (re)-creation of nodes in the TRW was done in EDT which led to freezing the UI when the user tried to show/hide passed/failed etc test cases. The behavior was changed to create the nodes as needed asynchronously in the changeset from comment 2. So, please try a latest build or wait for the final 8.0 version and this should be fixed. Thank you for reporting.
