2023Q1 packages, some Intel GPUs: Crash, Freeze in OpenGL initialization detected

[probonopd]

Since 2023Q1 packages, our KWin.app does not do compositing anymore on some Intel GPUs (e.g., on Intel HD Graphics 400).

[probonopd]

Built new KWin.app. Crashes on Intel GPUs with compositing enabled.

Same for FreeBSD kwin and kwinft packages, with BreezeEnhanced disabled.

What gives?

[probonopd]

On build 2H238, this issue does not manifest itself on Nvidia GPUs.

So maybe we also need to update graphics/drm-510-kmod... every quarter the same hassle, argh.

[probonopd]

No change.

On another Intel system, KWIn.app is not crashing, also getting these messages except for Freeze in OpenGL initialization detected:

Maybe @evadot has an idea how to debug this? E.g., to find out which component is causing the issue? Xorg log doesn't show any obvious errors.

[probonopd]

Intel UHD Graphics 620 (GT2) also does not have the issue.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=268955 tested workiing for HD 3000. Thanks Jan Beich.

[probonopd]

Works. Huge "thank you" to @jbeich for identifying the root cause, and for providing a fix. :1st_place_medal:
