Type Layer with some fonts (e.g. Bahnschrift) slows down After Effects to a crawl

[Micha908]

I am having this very weird issue (Win 10 / AE 16.1.2) where I add a type layer to a comp and depending on the font, everything goes smoothly or slows everything down to a crawl, with the AE task using up 100% of a CPU core (the one the UI is running on I presume) and AE becomes pretty much unusable.

I have noticed this for example with Bahnschrift vs. Arial. Arial is fine, Bahnschrift is not.

Has anyone else seen this and is there a fix?

Edit: this is after a fresh install with all preferences removed

I think there's something up with the Bahnschrift font.  Unexpected things can happen with any font, but they're more likely to happen with free web fonts.

I just downloaded it and I can't even get it to install.  The TrueType files preview as expected, but won't install.

Maybe try something from Adobe Fonts that's similar (Adobe Fonts | Explore unlimited fonts)?

Bahnschrift is supposedly the next default UI font for windows after Segoe UI (it ships with the latest Win 10 service packs too), so I'd assume/hope they would not do something weird there?

As noted earlier, fonts can act weird.  I see you compare it just to Arial but have you compared to a couple others to just ensure it's that particular font?  Then if so, perhaps delete it and reinstall or find another version of that font?

I suppose the simple answer is choose a different font so not sure how determined you are to use that one.

A fresh install will not overwrite previous Pref Files if you chose to Migrate Settings during the installation process. So, perhaps trashing AE's Prefs may help?
