iGPU throttling after waking up from sleep

[gvnix]

Hi,

I have been experiencing UI lag after waking up from sleep from I thing High Sierra. Only a restart fixes it.

To investigate I installed, intel power gadget.

1. When UI is lagging
GPU speed - 0.2 Ghz

2. When everything is smooth (after restart)
GPU speed - 0.75 Ghz

My Mac -
MBP 15in mid 2015, no dGPU.

What can I do to fix it?

I have the same issue, not to name the other 5 or so. Except my machine is the one with a dGPU

It's a shame this hasn't been fixed yet. I had no issues for 10 days. But today I put it into sleep with safari open with some video paused in picture in picture. After wake - same issue.
