Video and Thumbnail Colored Noise Issues

[Brian-Naja]

I've been having issues video and thumbnail noise when using the intel hd graphics and the discrete graphics together. I have tried Clover and Chimera and had the same problem on both. The issue goes away when I disable the on-board graphics in the bios but, that also disables the intel quick sync and my Final Cut Pro X exports take forever.

Hi, did you make any progress? I'm experiencing the same issue.

 

[Brian-Naja]

Nope, I even did a fresh install and still got the same graphics corruption.

Hi, I solved the issue in my case. Maybe it is just a coincidence but after adding the following kernel flags the coloured noise disappeared!

<string>kext-dev-mode=1 npci=0x3000 darkwake=0</string>

I just added them in the org.chameleon.Boot.plist

This did not work for me. Just upgraded to 10.10.5 on a Haswell CPU, GTX 770, GA-Z87X-UD3H motherboard. Have not found a solution yet. I suffer from occasional colored noise in youtube, thumbnail and preview photos, and videos off my SSD. Mostly just happens on startup using discrete GPU, I don't use the integrated as of right now. All 4 are not affected at once, sometimes youtube, sometimes thumbnail, sometimes preview. For youtube I can refresh the page and that fixes the issue temporarily. Kind works the same for preview thumbnails too. Slightly annoying but would like to resolve 100% Will be doing more research.

Did you find a solution for this? I have had this problem on a fresh el capitan install about 2 month now. Using Both IntelHD and GTX 780.

best regards!

In regards to salvaging that particular install the short answer is partially. I read on multiple posts that disabling the Integrated Graphics in your BIOS can fix the YouTube and Garageband distorted color noise issue, and if I remember correctly that worked for me as well. What it didn't fix was the thumbnail distorted color noise, but, I discovered that my media drive was formatted to ExFat and not Mac Journaled. I suspect that may have been a possible reason for the thumbnail color noise distortion but I can't confirm since I discovered it after I reinstalled 10.10.5 using clover boot. The ExFat format also caused Pro Tools 11.3.1 to freeze when double clicking on crossfades and Photoshop CC to freeze when saving my project. Once I reformatted it to journaled the program freeze issues went away.

Are you using clover or multibeast? I can report that I've have had a much better out of the box experience using clover. The learning curve is about intermediate but very worth it. I don't have distorted color noise issues or USB Kernel panics. Also the Messages app works now.
