--- Comment #7 from Vurefozu <konstantin.t.i@ya.ru> ---
FreeBSD 13.2
FreeBSD 14.1
FreeBSD 14.2

CPU: Intel i7-4770k
GPU: Intel HD Graphics 4600
Kernel module: i915kms

After switching from a graphical console to another console via CTRL+ALT+F1 and
back CTRL+ALT+F9, hardware graphics acceleration disappears.
