Comment 1 Aleix Pol 2011-10-09 14:29:40 UTC

Does this happen in master?

Comment 2 Adria 2011-10-09 14:31:46 UTC

Yes, it happened in Master (although it says KDE 4.7.2). I have the official Arch KDE packages, but KAlgebra from master

Comment 3 Aleix Pol 2013-06-01 00:17:06 UTC

Still happens, actually puts the cpu at 100%...

Comment 4 Aleix Pol 2013-10-28 12:19:53 UTC
