@burnout426 said in YouTube became a scrambled mess:

[...]if you can turn on hardware acceleration and find an Angle flag setting that avoids the problem and gives you hardware acceleration for things [...], you'll get better performance.

It seems that with hardware acceleration turned on, any D3D Angle flag setting would ruin the visuals (weirdly, first video after picking any D3D-related option looked normal, the issue would start with starting of another video). However, OpenGL works just fine.

So glad I don't have to sacrifice performance for normal visuals. Thanks again!

@burnout426 Initially, shortly after I made this thread, I figured out that the ImprovedTube extension had a lot to do with it. Strangely, after reinstalling it, I found the reason being the bluelight filter so I disabled it for the time being (though when I tabbed out of YouTube or opened the notifications the distortion kept coming back). As for Your advice:

• I had RGX disabled altogether, I never even thought of turning it on in the long term;
• Since mods were introduced not so long ago, I didn't even start browsing these;
• First, I adjusted the Angle flag. By default, it was set to "undefined" (which I believe was an error or something), so I set it to D3D11; this alone didn't work, so I disabled hardware acceleration, which seems to have solved the issue.

Thanks for help

Until yesterday, I could watch YouTube without any major issues. But today... * sigh * Better if you see for yourselves:

Just to be clear, I tried Chrome, and the videos looked completely normal, nothing out of the ordinary. Therefore, it's definitely not a hardware thing.
