Firefox messed up display

I am using Firefox on Linux. Version is showing as 114.0.2 when I do firefox --version. The display in the Firefox windows is completely messed up. Can't show what I mean as I probably can't get a screenshot. Is this to do with hardware accelerated video? These messages appeared when I tried it from the command line: "[GFX1-]: glxtest: libEGL missing methods for GL test Missing chrome or resource URL: chrome://global/skin/icons/warning-16.png" It starts and then has very high CPU. I had to reboot. I may have added something to the config in the past, using the GUI, but can't remember what I did, maybe to do with the hardware acceleration, thinking I could try seeing if it would work. I tried a few things adding these lines to a user.js file in the profile folder (something I found online):

"user_pref("browser.preferences.defaultPerformanceSettings.enabled", false); user_pref("layers.acceleration.disabled", true");

This has not helped. Is there anything else I can do?

I forgot to say there were some other lines on the output on the command line. I just picked out those as I thought they might be more relevant.

Just tried it again and there are many lines like these in the output: [Parent 21804, Main Thread] WARNING: gtk_widget_get_style_context: assertion 'GTK_IS_WIDGET (widget)' failed: 'glib warning', file /builds/worker/checkouts/gecko/toolkit/xre/nsSigHandlers.cpp:167

I appear to have fixed this by downloading the latest version. I moved the exist firefox/ folder under /opt. Then moved the new downloaded Firefox to /opt. Used instructions here: https://support.mozilla.org/en-US/kb/install-firefox-linux I am now on Firefox 123.0.
