https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=285516



--- Description ---
On FreeBSD 14.2-RELEASE amd64
with drm-61-kmod-6.1.92.1402000_3
> pciconf -lv|grep -B4 VGA
vgapci0@pci0:0:2:0:	class=0x030000 rev=0x09 hdr=0x00 vendor=0x8086
device=0x0122 subvendor=0x8086 subdevice=0x2003
    vendor     = 'Intel Corporation'
    device     = '2nd Generation Core Processor Family Integrated Graphics
Controller'
    class      = display
    subclass   = VGA

Flickering artifacts appear on screen that look to me as visible memory changes
suggesting that memory ranges for graphics are used by other applications. The
artifacts appear randomly when watching a video with firefox and also on other
windows on other work surface. 

See screenshot attached.
