Currently you are using radeon kernel device driver with radeon DDX Xorg display driver. You may switch to the amdgpu kernel device driver, which supports both the amdgpu DDX display driver and the modesetting DIX display driver. To make the switch, append the following to the linu lines in /boot/grub/grub.cfg and GRUB_CMDLINE_LINUX_DEFAULT= in /etc/default/grub:
radeon.si_support=0 amdgpu.si_support=1 Switching between the two Xorg drivers can be done via config file in /etc/X11/xorg.conf.d/ to specify either with a device line. Because it's happening in web browser, I'm guessing GPU overheat is likely the cause. Taking the cover off the PC and aiming a large fan at the interior may be telling. Make sure the CPU fan, if present, is working, and the heat sink isn't loaded with accumulated dust and tobacco tar. If it is, then the PS would need cleaning too, as there it could cause voltage instability from overheating. -- Evolution as taught in public schools is, like religion, based on faith, not based on science.
