I spoke too soon. The chrome editor webgl context lost error returned. The launched app however is fine.
It is odd that this error manifested suddenly today. I haven’t knowingly changed anything. The launched app is ok but the editor has the error even in a blank new project with no edits.
Is there a possibility that some changes have been made to the editor/engine in the past week or so, that would cause this issue to manifest on my mac/gpu combo?
Last year we has a lot discussion here and here about Macs and issues with with certain gpus ( all my 3 macs fall into this category ).
