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.

(SOLVED) Window Tearing(?) Issue on Nobara (sh.itjust.works)

EDIT

So anything I said below was all a lie, it turns out that the issue was kde and my monitors, which are 240hz. I swapped to gnome and the issue disappeared, and then I installed bazzite kde on a second drive and the issue reappeared. Setting my refresh rate to 120hz stopped the flickering and upon setting it back to 240hz I do notice an appreciable decrease in artifacting. I have no idea what to do with this information, but if anyone is experiencing this try just decreasing your refresh rate for your monitors.

Howdy,

Just installed Nobara again and am trying to figure out why this is happening. I think it's a firefox thing since I haven't seen it happen in any other application; basically anytime I do a lot of scrolling, the firefox window breaks down and I can see my desktop background behind it. It always happens in the bottom right cornerish part of the window. I'm up to date on all updates as far as I'm aware. I did some googling and checking out the nobara discord but I couldn't find anything related. I tried recording my screen via spectacle to show the issue, but it wouldn't capture the issue.

Any help would be appreciated; I am a linux beginner so dumbing down any info you have would be nice. Thanks!

Not sure if I'll be of help, but I can try. It would help to get some more information.

You're using the Breeze cursor theme, so I'll assume you're using KDE Plasma. The cursor looks like it's from Breeze 5, not 6, are you on the old Plasma 5? If you are on Plasma, you can go to settings and go to "System information" (near the bottom) or something like that. (IIRC, It was a long time ago since I last used it)

Are you using an Intel, AMD or Nvidia GPU?

Are you on X11 or Wayland? (They're different ways to handle windows, X11 is very old, but may work better in some cases. Wayland is newer, more secure, has some features that X11 lacks, like HDR & is usually better)

You can check the windowing system (X11/Wayland) by opening the terminal (the application Konsole on Plasma) and typing echo $WAYLAND_DISPLAY and pressing enter. If you only get an empty line, you're on X11, otherwise you're on Wayland.

If you're on Wayland, go to the URL about:support in Firefox. Then search (ctrl+f) for Window Protocol. This should be Wayland, otherwise it's falling back to a X11 compatibility layer called Xwayland.

Thanks for helping!

~~I'm on KDE Plasma 6.3.4 with Wayland, using an Nvidia GPU, 4080 super. Checking that about page, it says it's using wayland as well. I'm using flatpak firefox version 138.0.4.~~

~~I really can't peg what causes it. I have two monitors, and my non primary one seems worse than the other. My primary display will only do it occasionally, but scrolling through youtube on the other will basically always cause the issue. Like I said, I've only seen it happen with firefox so it has to be something weird with the install. Is there a different way to install firefox other than a flatpak? Googling that...~~

Ok, I'm not sure why I didn't try this, but I downloaded just the linux ...exe? Program? from the firefox website and it seems like the glitch is nonexistent on that version. My next question would be how different is that from the flatpak? What's the difference? Do I need to do something else for updates?

flatpak is basically linux's app store. flatpak is easier to install because it's just a button press and everything on flatpak is safe, and it handles updates for you, so try to use it as much as you can.
