I'm hoping someone has some answers/help for me. I tried the 'weird stuff/black boxes are happening' suggestions (switching to 'basic', and unclicking 'use graphics processor', then restart, to no avail.
I have a PC desktop running Windows 10 and Photoshop CC2017. It is under 2 years old, and has 16 GB of RAM. Its hard drive has 344 GB free out of 500 GB. The last time I shut down was just before posting this thread. I run a cleanup program about once a week. I have attached two pictures of what it looks like when I use the sliders in ACR. I can't capture a screen shot, as when I try to this stuff just disappears when I click outside of ACR. Sometimes the entire histogram is covered up by this crap when I'm trying to use the sliders. Could this be my graphics card, or not enough ram?
Thanks in advance!
