Only with Youtube videos, a thin red vertical line follows the cursor.
This started a couple of months ago and was never fixed through various updates.
That doesn't happen when using other browsers like Chrome or Edge.

The checkbox is what you would uncheck if you wanted to keep RGX/Lucid Mode on.

Thanks. Could you please provide the link to that setting?
My UI language is not English.

Thanks for your reply.
So, I switched off "optimize video quality" and the line is gone.
