Horizontal or vertical green border on videos
I have the same problems as the user in this thread has:
https://support.mozilla.org/en-US/questions/1164331
When playing videos, there's a green border in the video window, both in normal state and fullscreen.
My GPU is different than the GPU reported in the other thread, so I was asked to create a new question which I hereby do.
When I commented on the other thread, I was running FF version 55.0.2 and had a green border in the bottom of videos on YouTube (see first screenshot) and other video sites (e.g. teamcoco.com/video, see second screenshot).
Today, FF is version 55.0.3 and I now see a green border in the right side on YouTube videos instead (see third screenshot, notice YouTube changed the layout in between), but the teamcoco.com/video video still has the same green bar in the bottom. YouTube recently updated their layout, so this may be the reason for the change in behavior, or it might be the FF upgrade. I can't know which.
FF Version: 55.0.2/55.0.3 OS: Windows 10 Home (with all updates) GPU: nVidia GeForce GTX 260 with most recent driver (342.01)

At this point I have both a vertical and horizontal bar on YouTube.
See if there are updates for your graphics drivers https://support.mozilla.org/en-US/kb/upgrade-graphics-drivers-use-hardware-acceleration

Allow me to quote myself: "GPU: nVidia GeForce GTX 260 with most recent driver (342.01)"

And the other link?
Regarding the second link:
Yes, I have tried disabling all extensions and configure the Shockwave Flash Plugin to the setting "ask to activate" (or whatever it's called in English, I'm running the browser in Danish). The setting for the two other plugins ("OpenH264 Video Codec..." and "Widewine Content Decryption Module...") can't be changed). The changes didn't affect the issue.
Shockwave Flash is the latest version (v26.0.0.151), I expect the others are up to date also but I don't know how to check it as I suspect they came with Firefox which is up-to-date ("Widevine Content Decryption Module" is v1.4.8.903 and "OpenH264 Video Codec" is v1.6).
Also, the same solution works for me as in the other thread. I didn't mention it specifically but just wrote "the same issue". So just to make sure readers understand it: Safe mode and/or setting "media.windows-media-foundation.allow-d3d11-dxva" in about:config makes the problem disappear.
That was very good work. Well done. Please flag your last post as Solved Problem so others will know.
I am deeply sorry for misunderstanding what apparently was irony in the answer to my follow-up question in the other thread ("Since you have a different GPU, please open up a new question and reference this one. It is not the same issue, however same symptoms. Thank you for your help, and I look forward to troubleshooting yours. ") I read is as though someone was very interested in locating the source of this issue and trying to fix it instead of letting many users (20+) experience the issue and either live with it or having to search for help and make advanced configuration to circumvent the problem. Sorry for wasting everybody's time.
