Slow with activated case feature

Glyphs
1

Hi,

with activated case feature Glyphs is very slow. So I wanted to just paste a string with glyphs names to avoid activating those feature.

I have such a string :

НН/guillemetright.case А/guillemetleft.case НН НН/guillemetright.case

Do you have the Preview at the bottom enabled?

I can’t reproduce it. Can you send me the font and a screenshot of the edit view?
