Now I can reproduce it with revisions 166102, 166367, 166401, 166533, and 167096, but not with revision 162456 nor revision 167584. So the bug seems to have been introduced between revisions 162456 and 166102 and fixed between revisions 167096 and 167584. You are unlucky to be right where the bug is;-(I'll look later to see if I can refine the windows and try to spot the right pr). Meanwhile you should notify Gaurav Khanna about the bug and ask him if he his planning a more recent build.
