Material editor buggy as in UE 4.2.3

Hello,

Every since upgrading to 4.2., the material editor is just plain bugs. It basically “gives up” rendering and shows a checkbox texture when things get a bit complex in the material like using material functions and gives no errors why it is not rendering (Is there a log for this?). Also the stats tab is also broken when this happens.
