Weird video issue / chromium bug?



  • Hello, I've recently switched to Vivaldi and so far I really like it. Unfortunately I'm facing a weird video issue that started appearing under Opera, that I was previously using. Because it does not happen on Firefox but does on Vivaldi I suppose it's Chromium related, but I'd rather make a post here first for feedback. I also made sure my video card pilots were up to date (GTX 1060).

    Now onto the issue. On some videos, colors are completely broken as if under the effect of a bad chroma key. So far I've only experienced the issue on one series of videos/livestreams from ONE specific source, you can check this video https://www.twitch.tv/videos/278709777 to test for yourself. The problem only happens if the video is in source quality, and as I've said the videos from this channel (and the livestream) are the only where the issue happens for some reason.

    You can clearly see the problem on the following captures: First, how it looks in 720p (also how it looks on source quality under Firefox, the expected visuals)
    0_1530227928207_0292e77f-0190-41d2-ab9b-6502c338aa83.png

    And this one is what Opera and Vivaldi show on source quality
    0_1530227992990_daab5657-9298-4cfd-aecc-5798346d2c37.png

    You can clearly see how the blue is hollowed out in a weird graphical glitch. I've asked friends, out of three only one experienced the same issue on this particular stream. I suppose they are broadcasting using a specific setting/codec that isn't properly supported by Chromium. On a final note, the video player on twitch is full HTML5, so flash isn't concerned here.

    Any help would be much appreciated, thank you.



  • @xunkar Well, I can only check on Linux at the moment 😞

    The Video is about 4 hrs long!! However, those captures are from about 53 mins into video.

    I switched to source quality and then clicked on the time line to "jump forward". There is no problem with the display on with my system (Mint 18.3 with GTX 1030 - Nvidia driver 384.130).

    It may be a windows/driver specific problem, but are you using hardware acceleration in Vivaldi?

    Check what shows under the vivaldi://gpu [only the Graphice Feature Status section]

    I can't reproduce this error in Windows 7. Maybe a problem of your driver.



  • @tbgbe said in Weird video issue / chromium bug?:

    The Video is about 4 hrs long!! However, those captures are from about 53 mins into video.

    It doesn't matter the issue is present during the whole video, it's a permanent effect 😕

    I didn't precise, I'm using Windows 10 Pro, Vivaldi 1.15.1147.47. nVidia drivers are up to date, and the issue was already present before I updated them anyway. Here is the gpu report. I already tried disabling hardware acceleration to no avail.

  • A bit more info after running some tests, also with my friend who has the same problem: no issues running Chrome, however Chromium completely fails to load any video, gives an error 6000: Renderer not available...

    (PS: Sorry for the code block, I tried looking for ways to do it but there is no option for it in the message compose toolbar)

    I cant reproduce your issue on my normal NVidia GT 710.

    Must be NVidia driver issue for your graphics card.

    Did you check the new 1.16 Snapshot if it solves the issue? You can install it as Standalone (Installer Advanced) on your user space.

    You are welcomed to report it as a bug so developers may check if tehy can reproduce it.
    Please read how to Report a bug for Vivaldi carefully and then report the bug to Vivaldi bugtracker.



  • I wish it was just a driver issue, but my friend has a GT 680 and has the same problem.

    You may not be able to tell from the two screenshots but the problem is actually two-fold; some colors seem hollowed out, and the whole video is much darker too. I tried the latest Vivaldi snapshot, the first problem is fixed, but the dark hue remains.

    Please try for a test do deactivate video decode acceleration:
    Open vivaldi://flags/#disable-accelerated-video-decode
    Set to Enable
    Restart Vivaldi

    Or it is a color profile error?
    Open vivaldi://flags/#force-color-profile
    Select sRGB
    Restart Vivaldi



  • Oh, when I tried disabling hardware acceleration I went for chrome://flags/#disable-accelerated-2d-canvas I did not know there was a flag specifically for acceleration of videos, what a bummer. Turning vivaldi://flags/#disable-accelerated-video-decode off however DOES fix the issue.

    Still, it's surprising that hardware acceleration causes this issue on only one video on the internet (so far as I've tested). And Chrome's acceleration does not have this issue either. Well I hope this can get fixed, but it's a fine workaround for now, thank you very much.



  • @xunkar said in Weird video issue / chromium bug?:

    And Chrome's acceleration does not have this issue either

    Well Chrome uses licensed codecs unlike Vivaldi and Chromium (who can't afford the fees) so use free/open-source codecs.



  • Now that hardware acceleration is disabled, I experience crashes after about an hour of video, the whole page just blanks out with the dead bird icon.

    @xunkar Then open vivaldi://flags and Reset them to default.

    And you may report the issue with the wrong display/glitch on Vivaldi.
    Please read how to Report a bug for Vivaldi carefully and then report the bug to Vivaldi bugtracker.



  • @tbgbe Nope, Vivaldi taps into the default codecs that come with Windows, no other installed codecs, so they are restricted to what those support.

    Support is different on different Windows versions, e.g. webm, what YT uses, can be hardware accelerated only on the latest versions of W10, the same as some high settings of h264.

    Vivaldi and Chromium include the free codecs though, so those should mostly work fine.

    Other than that: NVidia has several known problems with their drivers since about 2 years - especially with artifacts and scaling - and as far as I know they did not bother to fix all of them until now. (Can't say for sure, I ditched NVidia at some point because they broke stuff one time too often for my taste.)



  • @gwen-dragon I can confirm this bug on Linux too.
