i915kms: artifacts with overlays on top of video playback in chromium+youtube

[erikarn]

Describe the bug

There are artifacts with overlays on top of video playback - with youtube, when watching videos it's fine, but when you mouse over the playback window to manipulate the controls, you end up with horizontal banding.

This didn't happen with the -HEAD install I had here from a few months ago. (Yes, if requested I can actually go grab the ports tree and FreeBSD-HEAD version as I still have the installation media..)

FreeBSD version

it's -HEAD, ff06a8dbb677a04 (Aug 19, 2022 commit from jhibbits, but it's from the tree @ Jan 22 2023)

PCI Info

pciconf -lv

(It's a Haswell-ULT - vendor 0x8086, device 0x0a26, subvendor 0x106b, subdevice 0x011b)

DRM KMOD version drm-510-kmod 5.10.113_8

To Reproduce

• fire up xorg
• fire up chromium
• watch youtube :-)

• Screenshots

  

Additional context

This is on both a macbookair6,1 and macbookair6,2, which are similar era computers.

Is this with libva-intel-driver installed ? As said on irc this kind of regression is hard to track as it might be from drm or mesa or something else ...

Ping for the question about libva

Closing as no news.
