Description Aron Budea 2021-12-29 19:33:59 UTC 
This bug is probably specific to Intel IGPs, or a subset of them. Tested with a 2018 Mac mini (Macmini8,1), running macOS Monterey.

With an empty profile, start LO. In the About dialog, you will see:
"UI render: Skia/Metal"

Now check Tools -> Options, and View settings, and you will see that Force software rendering is ticked. And indeed, after restarting LO, UI render is now Skia/Raster.

If the IGP can't handle Metal completely that's fine (I didn't notice glitches during the first start, but I haven't checked in great detail), but it's a bit strange how UI render isn't switched to Skia/Raster right away.

This doesn't make sense. The force-raster option is enabled only before crashing, so it should not be possible to see this, unless you've set the option yourself and then didn't restart LO.

I retested with a daily build from ~2 weeks ago, and Skia/Metal persists now.
Closing as WFM.
