Window flickers when selecting points

I was working normally today when I noticed that my screen was flickering whenever I tried to select points for an extended time in Glyphs. Has anyone experienced this?

I’m noticing that this happens whenever I extend my pointer selection outside the bounds of the metrics (ascender/descender).

What version of macOS do you have?

Oooh I have just updated to the latest Sonoma version

I expected that. There seems to be something going on in Sonoma that can cause this. We had reports about similar issues.

We are looking into it.

What type of mac do you have (Intel/ARM, what graphics card)?

^^mine is Air with M1 chip

Happened to me too, except while zooming in-out using mouse scroll wheel+cmd, zooming using mouse scroll wheel+opt seems quite normal.

macos 14.0, MBP M1

Same here. Also, the display is somewhat blurry most of the time.

Happening to me too.
