Same problem in cutting edge version for me ( 2.52 ).
I haven’t noticed any particular zoom level where it gets stuck; it’s seemingly random. Just now it got stuck at 1500, but I’ve had it stick at both larger and smaller sizes. Not always, but it’s even stayed stuck when I’ve quit the app and relaunched it. The only thing I’ve found to reliably unstick the zoom is to select View > Zoom to Active Layer.
I’m not familiar enough with the console app to decipher all the data there. There are some user report items regarding Glyphs crashes from earlier in May, but they don’t seem related to the zoom hangs. There are several QuickLookSatellite crashes from the past two days that are related to Glyphs. I can’t really say that I know what I’m looking for.
Can you try running without two of these, and if it gets stuck again, disabling the two others. And if it does not get stuck anymore, to reenable one of them. That way you should be able to find out if one of the plug-ins cause the problem, and if so, which one.
It seems the Zoom-In freezes even when all the above list is De-activated:
Now I quit Glyphsapp and relaunched … by opening any glyph window it remembers that and still stuck on 6003 pt. no way to change!!
The last attempt was by relaunching with Shift which I believe neutralizes all plugins … this time i got control on Zoom in.
I’ve been keeping up with the cutting edge versions, and haven’t had a zoom problem since June 5 or 6. Previously ran into problems every 2 or 3 hours. Currently running Version 2.5.2 (1148). Problem solved, I hope.
