Apologies if this is more appropriate for the subreddit, but my question felt supportish.

Anyway, I just stumbled across elementary (mac user since I was like 7) and decided to give it a shot last night.

Really liking it so far, but I woke up this morning to a noisy desktop background image:

Noisy desktop bg

I toggled the desktop image, which fixed the bg image besides a few pixels in each corner and the multitasking background:

Screenshot: errors in corner pixels Screenshot: error in multitasking background

Basic environment info:

  • elementary OS 0.4.1 Loki
  • Dual booting on a 2012 iMac
  • Quad-Core Intel Core i7-3770S CPU @ 3.10GHz
  • NVIDIA Corporation GK107M [GeForce GT 650M Mac Edition] (rev a1)
  • I'm using the nvidia-384 driver available through AppCenter.

Similar problem comes to me every time when my computer returns from suspend.

I cannot say that it is a nice solution, but I found that there's no problem if I switch to the Intel GPU(Power Saving Mode) from the NVIDIA X Server Settings app. enter image description here
