Weird trim behaviour

Bug reports

Please view the attached video, forgive me for the potato quality but i was tryimg to get within the size limit.

This has never happened to me before, the shape is hollow if trimmed and generate some weird…. Artefacts? Geometry?

Update to 1.78?
I can’t see if you are on 1.77.

:woman_facepalming:t2: oh ya that did it- my bad, I was wrongly assuming I was on rhe latest release because I have autoupdate on.
