Safari videos are corrupted in High Sierra

Some videos are corrupted when playing in Safari. Doesn't happen in other browsers (Chrome, etc).

Videos get all jagged, like they're being split in bars, and colors get messed up, the rest of the website's content is fine, just the videos get scrambled. Audio from the videos play normally. Also happens sometimes when I open videos directly in Finder.

Here's a screenshot of what happens:

Anyone else seeing this problem?

I'm on a Macbook White, running High Sierra.

Safari/Preferences/Advanced - enable the Develop menu, then go there and Empty Caches. Quit/reopen Safari and test. Then try Safari/History/Show History and delete all history items. Quit/reopen Safari and test. You can also try try Safari/Clear History…. The down side is it clears all cookies. Doing this may cause some sites to no longer recognize your computer as one that has visited the web site. Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library/Caches/com.apple.Safari/Cache.db and move it to the trash.

Triple click the .plist file path written in bold letters below to select.

Then right click on it to get the contextual menu.

Move the mouse pointer to “Services” and then click “Show in Finder”.

Finder window will open up showing com.apple.Safari.plist highlighted.

Right click on it and choose “Move to Trash” from the contextual menu.

Quit Safari.

~/Library/Preferences/com.apple.Safari.plist

Restart.

Launch Safari and test

Customize Safari preferences the way you want.

Safari > Preferences > Extensions

It was already unchecked. Out of curiosity, what would that have to do with corrupted videos?

Saw in another forum a lot of people with the same problem. Looks like something to do with the graphics card 9400m and its drivers on High Sierra, but still no answer.
