Problem Description:
I open a Brave web page noticing now that the ?Lion used by Brave cab be black, not its usual red. I select the menu and the web page disappears. I click on the top to move the page and it disappears. I select a favourite from the ‘bar’, and the drop down window will disappear most times, or a folder in that drop down will open then shut. These make the web page unusuable. It appears to improve with time and become more stable. It also occurs with Firefox.
Relevant System Information:
NVIDIA GA 106 [GeForce RTX 30360 Lite] with driver nvidia-driver-580-open (proprietary tested)
What may or may not also be a symptom is that the panel is slow to return at times and I have to wait for it to show up again. When closing down the options are very slow, some times a minute or so, to show up.
What I’ve Tried:
Re-installed Brave browser. Checked journalctl --unit=fstrim.service:
This happens with both Brave and Firefox so has it been happening since your install of Ubuntu 24.04? Did you have an earlier OS on this same computer and have the same problem? Do you not have this problem on windows? NVidia cards are excellent on windows but are notoriously problematic on Linux and my understanding is that you need new drivers on each kernel upgrade. Hopefully, someone with more familiarity with Nvidia will post.
I’m not asking about the browser. Does the issue you are experiencing happen with specific websites or is the issue occurring with any website you choose to visit?
This sounds like Wayland issues, which tracks with Nvidia hardware being used. Early on, when Firefox only had experimental Wayland support I saw similar “disappearances”, when the context menu opened but was invisible.
Try running in X11 mode. Firefox knows the environment variable MOZ_ENABLE_WAYLAND; setting it to ‘false’ should allow you to run:
MOZ_ENABLE_WAYLAND=0 firefox
from the terminal. That then starts FF in X11 mode, which in turn uses XWayland. If that doesn’t do the trick, you may need to log out and login to an X11 desktop session.
Thank you but I would need step by step help there. I have no doubt I can do it but at 87 without any real knowledge I am loath to ‘Interfere’ as at least it is running, without guidance.
You can start here, to get to a terminal. Then you copy the command from my previous post, e.g. by clicking the little clipboard icon in the top right corner of that “code” element, which appears when hovering over it with the mouse. Then you go to the terminal and “paste” by simultaneously pressing CtrlShiftv, or right-click with the mouse and selecting “paste”.
Make sure Firefox is not running already, otherwise the above command will just attach a new window that session and ignore the environment variable.
See where that gets you and we can iterate from there.
I was about to follow your instructions when I realised you were referring only to Firefox. I use Brave 99.9% of the time and only tried Firefox to see if the problem appeared there. It did but not to the extent as it did in Brave which is virtually unusable.
Will your suggestion also have an effect on Brave which I can check?
That’s precisely the intent here. Try with FF in X11 mode and if the problem goes away we’ll take it from there.

That depends on the test results. Since usually Nvidia and Wayland don’t play nice together, chances are that you just need to login to an X11 session for your desktop. There should be an option for that, but you may need to logout first and manually select that. I haven’t found the tutorial on that yet.
