+
+Steps to reproduce the problem:
+1. Compile and run the attached files
+
+Actual Results:
+Backtraces, windows not displayed properly and slowly.
+
+Expected Results:
+No backtraces.
+
+How often does this happen? 
+Always.
+
+Additional Information:
+if i unset MONO_THEME it's still happening, so it's not the reason (my
+first guess).
