Hi everybody.


I have this really weird problem with my hackintosh.

I have these strange looking patterns in safari, but only there. They look like this ...

Has anybody a similar problem? The graphics card works fine in any other application. Benchmarks look good to me.

I don't have any problems when I boot into windows 8.

I'm using a MSI GTX970 with WebDriver-346.01.02f02.

I hope someone can help me with that.

I also get these and it is only occasionally. Sometimes refreshing that page fixes them. Also it is generally only the thumbnail, if I click to view the full size image it shows up fine. I am also using a MSI GTX 970 with those same web drivers but it started happening since I built the hackintosh and was running 10.10.1. I haven't found a fix and assume it is driver related.

Thank you very much for the prompt reply.

I think it's a driver problem as well because only the thumbnails are affected.

It's good that I'm not alone with this problem.

I hope nvidia is going to release a driver soon that will support the maxwell generation natively.

Nevertheless it's astonishing how smooth a graphic card can run on a generic driver.

Off-Topic:

Have you tried the benchmark CINEBENCH R15? I'm quiet curious about your score because apparently we have quiet similar hardware. Geekbench results are almost the same.

I had never ran it before but here are the results:

I don't know what a good or bad score would be.

Thank you for the results.

I achieved the best results after a clean restart. My results are:

There is still a lot of clearance for optimization I guess because I did the same test on Windows 8.1 and the difference was rather big.

I have a GTX 750 and I've started seeing a few minor screen glitches, which never happened until I updated to the latest Nvidia WebDriver (346.01.02f02). I guess it's a new bug they've introduced. But I can't easily go back to an older version since I'm on OS X 10.10.3 (yes, I know about the hack where you modify a .plist file in the driver to fool it into thinking you're running an earlier OS version, but I don't want to bother with that).
