Firefox flicker after making Radeon GPU the primary display renderer
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 . . .
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 . . .
