Vertical tearing due to window in the background

I noticed this today. When there's a scrolling terminal window behind Firefox, there is some tearing on the vertical edge of the window that's in the background.

I'm running KDE 4.13 (just updated today), Nvidia 337.12 from the official repositories on a GTX580.

Here's a small movie that demonstrates it: http://youtu.be/hLT5nrCog_g

Has anyone seen this or know whether there's a fix for it?

Do you have VSync enabled in your video card?

Yes, but thats a different thing. Have you seen the movie?

When you have vsync issues, there will be a horizontal line as a tear. This tearing is vertical, it a completely different thing. This is some kind of graphical glitch when 2 windows overlap.

Creepy sounds on the video :o

Anyway, you didn't mention which window manager & gfx card/drivers you are running, both are kinda important

Re: Vertical tearing due to window in the background

My son was playing Guild Wars 2 in the back . I wanted to delete audio but I didn't have the tools available.

Anyway, to answer your question its KDE 4.13 (just updated), latest Nvidia drivers from the official repositories on a GTX580.

The problem doesn't exist on my laptop, intel video running OpenSuse/KDE.
