Machine: Dell Inspiron 15 5567

CPU: Intel i5-7200U

Op Sys: Ubuntu 24.04.1 LTS

RAM: 16GB

GPUs:

(1) Integrated Intel(R) HD Graphics 620 (KBL GT2)

(2) AMD Radeon R7 M445


Soon after installing Ubuntu 24.04 LTS freshly into my laptop I followed standard configurations to set my graphics card as the primary display renderer for my machine.

This is done by setting the environment variable DRI_PRIME=1 in my .profile file and rebooting.

I also made the following settings to Firefox's about:config 

         layers.acceleration.force-enabled               true

        gfx.webrender.all                                           true

After reboot I get a lot of flicker on Firefox and a lesser amount on Thunderbird. The image below flickers on and off the screen for 1-4 seconds.

No such flickering occurs on Chrome browser.

Is there any way to fix this flickering ?

I notice that disabling Wayland and reverting to X11 eliminates the flickering.

Why is that, I wonder . . .

Korisno?

I can't say I'm surprised that there is no response to this from Mozilla staff. But I am surprised that no one else has noticed the way Firefox cannot handle Wayland on Ubuntu 24.04 . . .

Korisno?
