Hey friends,

I have found that only a handful of people have this issue (or maybe many people have the issue and simply don't notice it). I have also never found a proper solution. So I'm wondering if you guys are running into the same problem. (And if so, if anyone has figured out a solution).

Here's the problem: I'm using the GTX 1080 with the most current Webdriver, and in Google Chrome, videos are shown with the incorrect gamma. Shadows appear brighter than they should. This happens with all the video sites that I've tested (YouTube, Facebook, Vimeo, my Plex media server).

I ONLY have this issue in Google Chrome. I don't have the problem in Safari. (But I need to use Chrome for my work, because Safari doesn't display 4K FB videos, nor does it display 4K60 or 8K YouTube videos). So in short, I'm stuck with this issue, and it's impeding my work.

Here are some examples. Left image is Safari, right image is Chrome. You'll notice that the problem is more noticeable with darker videos (such as the Blade Runner 2049 trailer). But it's still visible (and annoying) with brighter videos.

It also may be important to note that I ONLY have this problem with videos in Google Chrome. Still images and text all seem to be fine. I also do not have this issue on my MacBook Pro or in Windows 10. Only on my desktop in macOS Sierra.

Disabling hardware acceleration in Chrome fixes the issue; however, I need hardware acceleration to view 4K and 8K videos, so that's not a proper solution.

Anyone else having this issue?

Anyone have a fix?

Thanks so much for your help!

Do you have a different GPU to try?

Perhaps the new nvidia drivers have a not been tested completely with WebGL.

Could be. That would be a logical explanation...

Here's something else that's really odd though. Now that I go back to my MacBook Pro, it's having this same issue. (But yesterday, my MacBook Pro did not have this issue!). Could there be some invisible setting in Chrome that accidentally got toggled on my MacBook as well? (I am signed into Chrome with my Google account on both computers). It's very annoying... :(

Sorry that I can't be helpful but I have the experience that Google Chrome just somehow handles color fundamentally differently. If I now open Safari and Chrome side by side, Chrome has this very Windowsy feel, all the colors are exaggeratedly saturated and full of contrast. Some very fine hues replicate very differently between the two. However, based on this experience, I would've expected Chrome to produce stronger contrast, yet you're experiencing its blacks to be less intense instead. I can only confirm that a distinct difference does exist and it's not just you.

Does anyone know if this issue has now been resolved with 10.12.5 and the new NVIDIA driver?

You guys may be some of the only folks using chrome with cMPs and newer nvidia cards - it may fall to you to be the test mules.

Call me crazy, but maybe updating the software and drivers would provide you with the answer?!

I will, once I have the need to go back to my macOS partition for something. I just figured if someone knew the answer then it was at least worh asking.

Really? You don't think anyone else with Pascal cards would be using Chrome?? It's kind of the standard go-to browser these days...

Out of the possible dozens of people using Pascal cards in cMPs at the moment, I don't find it at all hard to believe that only a few are using Chrome.

+1 I only use Chrome if I need to access a Flash site.
Generally I think people using Macs have embraced the ecosystem, they have an iOS device, and see the benefits of continuity, bookmarks syncing, etc that comes with using Safari on all their devices.
Safari is a pretty decent browser these days and there's not much reason to switch to Chrome IMO.

Call me crazy but the 2 screencaps look pretty much identical on my calibrated Eizo display, the difference is negligible. That's not to say you don't have issues! Some browsers support colour management some don't maybe some of your problem is in that area rather than drivers?

My monitor is calobrated as well. The difference between the two is HUGE. Black is supposed to appear black, not grey.

It's not a nvidia issue, color rendering is different from browser to browser.
I am an amateur photographer and when you look pictures on flickr or check your own jpg exports in chrome they look like complete ****.

For some reason the chrome engine resets horizon lines, de-sharpen your pictures and changes contrast. It's probably the same with video content.

Look at this B&W picture of Rockefeller Center, left is chrome, right firefox. In chrome it's completely unsharp and slightly washed out. It's the same jpeg ... but chrome rendering engines are ****.

EDIT: Just opened this thread in Chrome and it's even worse ...

Can you provide a link to your picture? I tried a visually similar picture, and it looks the same in both Chrome and Firefox (on Windows 10 though). Maybe this is a problem specifically with Chrome on MacOS, but I'd like to try with the exact picture you tried.

On macOS the photo you provided has the same issues in chrome vs firefox: Unsharp edges, horizon partially reset and attenuated contrast. The difference is shocking.

For reference, this photo is not 100% sharp but the difference on macOS in chrome and firefox is just crazy.

EDIT: actually I'm tweeting this to serious photographers to have their opinions

It looks like the difference is coming from the "zoom". On my cMP (as per my signature). I can clearly see the difference between Firefox and Chrome ONLY when the picture is resized to fit the screen. If I enlarge the picture to 100% (native resolution), I really can't tell the difference (may be because the picture is not 100% sharp from the beginning).

Can you tell which side is Chrome, and which side is Firefox?

You might file a bug report. I've filed two bug reports with Google, one for Chrome and one for Maps, and they've fixed both.

The Chromium team are unbelievably responsive.
I recently asked if they could add Windows Server group policies to block browser history deletion and they did it for me. Truly amazing dev team.
Definitely worth a shot.

I can tell chrome is left because the crop angle is not right. The change in contrast is less obvious.
