I am currently having issues with Youtube, Netflix, and vrv.co, all video streaming sites over on Firefox, though only in full screen mode, and only on those particular video streaming sites, and I don't know why. As everything else works perfectly fine on my computer otherwise. Though curiously, running the browser in safe mode seems to remove those issues. However, I suspect this is some kind of glitch in the browser. Strangely, safe mode removes the issue, but again, not sure why. I did check another browser— Namely Waterfox Classic. That worked fine. And so far the only suggestion anyone has had from the tech service that I have on the machine has made that makes sense is that this might be a video driver issue. I did just recently update my drivers, this is true. However the issue did not start up until a few days after this had occurred. I tried reinstalling the driver to see if that would fix the issue. The issue itself is very weird. It seems like the first third of the top of the screen is suffering from some kind of distortion that looks somewhere between pixelation and screen tearing, while the rest of the video usually plays normally. What's weirder is that this isn't consistent. Sometimes it will occur near the bottom third of the screen, and sometimes it won't happen at all. The only things so far consistent is that a) it happens only in full screen, and b) it only occurs to me when I'm in the browser on those sites. Nothing text based (i.e. Fanfiction.net) has this occur, nor does it occur on my games that are on my system via steam. Even weirder, having a secondary monitor attached causes the playback issue to vanish, as does having a remote repair attempted on it—which I did try to do when this first started— only to return again when the remote connection is shut down or the external monitor is unplugged from the laptop.
Again, Waterfox does not seem to have this issue. At first it was suggested to me on another thread that the issue might be because Waterfox Classic doesn't use hardware acceleration, so I turned that off on Firefox. Which does allow things to play more or less okay, though at times when I scroll, it seems to mess with the screen in a similar fashion to the initial playback issues, and again, it's not consistent with that, just like it's not consistent with the video playback when the browser's Hardware acceleration is on.
However, I just learned that Waterfox Classic /does/ use hardware acceleration, though it seems to have a much lower content limit set by default. This makes me think that whatever is going on may be a glitch in Firefox itself that may have somehow come up. Though how and why I have no earthly clue, as prior to last Monday there was no issue, as I said earlier. More unusually sometimes the effect vanishes on videos where it's shown up.
I have tried to screenhot this and it /never/ appears in screenshots, and doesn't show up when paused either. I've even tried to take a picture of it with my phone or record it with said. Also no luck. I /have/ however, been able to find a video that does this affect deliberately, so I can at least present it here. Again, this is not consistent, seems to move around the screen, and only seems to occur on those three video sites as I stated. Apparently whatever the issue is, it's /NOT/ something to do with the hardware acceleration, as I learned, again, that WaterfoxClassic /does/ use it and it is active in that browser, and was active when I first tried it, so that narrows it down to some kind of glitch either with Firefox or Windows and how it interacts with either the former or the latter, depending on where the glitch is coming from.
Does anyone have any idea what's causing this?
The image attached is an example of what I'm seeing, however, bear in mind that this video is /deliberately/ showing this effect in an attempt to replicate the type of thing one might see on old video tapes being played after years of disuse, but it /is/ the same general appearance, more or less, of what I occasionally see on Firefox when using the videos on the above mentioned sites.
