From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Weird ass line in the middle of my screen sometimes (Fedora Linux) (hexbear.net)

Finally back on a gnome distro that supports GRUB2, and loving it so far. The exception being that every time something moves, there is a weird line in the middle of my monitor that almost "splits" the screen in half, like it's off by a pixel or something. this isn't really present in static images though. it's pretty infuriating. when trying to record an example to share with you guys, i noticed it for whatever reason just doesn't even happen while recording my screen with GPUScreenRecorder. Does anyone have any ideas on what this could be?btw, this didn't happen on mint when i was using that distro. Thank you!

Sounds like you're experiencing screen tearing, an effect where the refresh rate of your monitor can't keep up with your graphics card. This section of the Arch Wiki might be helpful.

What kind of monitor do you have, and does it have a configurable refresh rate?

This fix is applicable only if OP is using x11 and not Wayland.

shit, you're right. I'm unfamiliar with Fedora and Gnome. I also found this thread in the NVidia developer forums describing what sounds like the same issue with a similar setup, but the proposed workaround doesn't sound feasible.

i have an msi g something monitor, goes up to 165 hz. And it's configurable, or at least i'm pretty sure. i changed it from 60 to 165 after i installed fedora, but i did that through fedora's gui
