Firefox flicker after making Radeon GPU the primary display renderer

         layers.acceleration.force-enabled               true

        gfx.webrender.all                                           true

'''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 ?
