WT? Help with display problem please...

[SpeedFleX]

I don't know can someone maybe tell me what this could be? It looks like overheating GFX but maybe it is really just a Software bug (I hope)

After this appeared I couldn't do anything and had to force a shutdown

You can try restarting and see if the problem goes away. If it doesn't, looks like a fried 9400M which will get you a logic board replacement.

yes it is gone now could it still be a hardware error or high temps? Or maybe it was just a bug?

Could be due to abnormally high temps.

Were you doing something very GFX intensive? You can install iStat Pro to run as a dashboard widget and that has a GPU diode temperature readout field.

Do you have the option to add "northbridge" to that list. IIRC, the 9400M is the Northbridge as well in these chipsets.
