Glyphs sluggish using excessive amounts of RAM

v3.3 (3331)

Since the latest build Glyphs has been slow even with only one open font and a single open tab with three or four lines of text and ‘calt’ active, now my system reported that I’ve run out of application memory because Glyphs was using 74,5GB, which doesn’t seem quite right. Anyone else having similar issues?

BTW I’ve tried to start the app with plugins disabled with no discernible effect. It seems to be related to calt, which has been troubling the app in this font in various ways for a long time, but as it compiles I have no means of identifying any problems in the OpenType layout.

I had one report about this but was not able to reproduce this.
Could you so a screen recording where you work in Glyphs but the Activity Monitor is visible (in money mode). So that I can see what you did when the memory goes up.

I’m sending you stuff directly.
