[Bug 267915] x11-wm/mutter: after graphics/mesa-* 21.3.8 -> 22.2.3 update OpenGL compositing fails on Intel Iris Pro

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=267915

--- Comment #37 from Vurefozu <[email protected]> ---
> When I change TTY to any other than vt9 and then go back to X11, I lose hardware acceleration.
FreeBSD 14.1
FreeBSD 14.2
CPU: Intel i7-4770k
GPU: Intel HD Graphics 4600
Kernel module: i915kms

I solved this problem with the loss of intel hardware acceleration via
xorg.conf. I added "DRI" "3":
/usr/local/etc/X11/xorg.conf.d/xorg.conf
Section "Device"
        Identifier "Card0"
        Driver "intel"
        Option "DRI" "3"
        BusID "PCI:0:2:0"
EndSection

Anyone who has this problem, please check this configuration and report the
results here or on the forum
