Hello,

I've installed Sierra with a Intel HD530, and as it is known, there are some graphics glitches. So, I decided to install and old GeForce 9400 GT, and it works almost perfect.

My mobo is a Gigabyte Z170X-UD5, with a I7 Skylake.

With some applications as iMessages, HipChat, Preview, etc. kernel dies with the following error:
virtual IOReturn IOGraphicsAccelerator2::newUserClient(task_t, void *, UInt32, IOUserClient **): Too many contexts (330) or command queues (1) created, possibly leaking?

Does anyone know where can I start looking for the solution?

Thanks!

I have this issue as well and it looks like it causes freezes in Sierra
