fdisk2k, does exiting fullscreen and then re-entering it remove the line?

I have had issues with lines appearing at the top of a fullscreen video for a while now, and this works for me.

Unfortunately I do not know of a solution aside from this workaround. Hopefully someone else does?

Hello ThechHorse,

Tried your suggestion, thinking it was a "refresh or artifac" , but it doesn't work. Tested on a virtual machine running Linux, tested in a 128 Firefox version and works perfectly, tried with Waterfox, no problem; tested in my main machine (OSX) with Google Chrome :/ and no white line on top.

Hope a 129.01 version fixed it. Thanks anyway fro your idea.

Best,

George
