Red dots in dark areas of images with hardware acceleration enabled

[Myrkrider]

Since the last update to 1.13 I now have the above described problem. The red dots do only appear on images, not in videos (e.g. youtube). See the pictures below.
With HW acceleration disabled the red dots disappear. Firefox and Edge do not have this problem and I can play games and watch videos without any issues, so I rule out a failing graphics card or faulty video RAM.
Any ideas how to solve this? I'd rather use HW acceleration. It seems to me, video playback without it is somewhat less smooth.

My specs:
Win10 Pro Ver. 1709 64bit
Intel Core i7 5820K@stock speed
nVidia GTX1080 (driver ver. 388.13)
16 GB RAM

Just tested it with the latest nVidia driver (388.31). The problem persists.
It also occurs on all websites. Interestingly, I've made a screenshot with the built-in tool of Vivaldi, and suprisingly no red dots are visible. I've made another screenshot with the Windows snipping tool from the same webpage:

I'm now running the latest snapshot (1.14.1072.3), and the problem is still there. And since GOG updated the chromium engine of their Galaxy client, I now experience this bug in Chrome, Vivaldi and GOG Galaxy. It is really annoying. Is there anybody out there having the same problem? I can't be the only one now, can I?

by googling nvidia+red dots on screen you can find many having or having had same problem, which appears HW related (temperature, broken card, etc)

@ian-coog I doubt that the problem is hardware related. The red dots only appear in browsers/apps that use the chromium engine (Vivaldi, Chrome and the GOG Galaxy client). I do not have any graphical issues while gaming, watching youtube, using Lightroom or browsing the net with Firefox or Edge. Maybe it is a driver issue, though if the fault lies with Nvidia or the chromium devs, I can't say.

So, I've found something new about my red-dot-issue: it seems to be somehow connected to my color profile. When I use a preset .icm-file provided by Windows the problem disappears, while using my calibrated profile seem to cause the red dots.
Now, I think I've read somewhere that chromium applies some sort of post-processing to pictures as to make them appear more saturated or something to that effect, and overrides the color profile. Is it possible to disable this function seperately or is it tied into the hardware-acceleration?

@gwen-dragon said in Red dots in dark areas of images with hardware acceleration enabled:

Try this:
Open in adressbar vivaldi://flags/#force-color-profile
Select an profile for Vivali from dropdown

Thank you, this did it! Works like a charm now!
