Preview shows bunch of noise instead of images

[drinkius]

Hello everyone,

Tried to find similar thread but couldn't, thus creating a new one.

When I'm trying to open some of my images - preview won't show it - just the noisy picture like the one below. Same happens when I open the images pressing the spacebar, but after pressing it two more times - it might as well show the real image. No patter seen.



My setup is:

OS X El Capitan 10.11 (15A284)
Gigabyte GA-Z97N-WiFi
Intel Core i5 4690K - Devil's Canyon
Gigabyte GeForce GTX 750TI (NVIDIA Web Driver: 346.03.02f02 + CUDA Driver 7.5.21)
Crucial Ballistix Tactical (16GB)
Samsung 850 EVO 500GB
Trendnet TEW-624UB v. d1 (USB WiFi)

A little update: I'm using an old SHARP TV connected via HDMI as a display and it doesn't show the original image properly (desktop doesn't fit the screen), thus I'm using a scaled image at 720p. It looks ugly, to be honest, and may be the problem is with the pixel grid or something like that.



I've changed the preview settings to "Size on screen equals size on printout" instead of "1 image pixel equals 1 screen pixel", all is working good so far.



My guess is - as soon as I get a decent display - the problem will be fixed.

New display, issue persists. Investigating further.

What system definition are you using?

Try Disabling your intel integrated graphics. It did the trick for me.

Thanks a lot for the help! Just switched off the Integrated Graphics in BIOS and the issue seems to be gone, at least at first glance.
