Hi There,

My MacBook behaves bad after display wakeup. Only the build in display wakes up, stays dark gray and the machine freezes completely. Accepting no inputs and doing nothing by unplugging the external monitor.

I am getting the following logs:

Especially this (com.apple.DumpGPURestart): seems to be odd. Also I am getting graphical glitches like that one, when using 3D:

Any help would be appreciated.
