This sounds a bit like the problem reported by Monterey users (except you’re running a very old OS version and presumably not an Intel GPU). @shooj said they made a backend change to enable the Metal version of the app for some Intel mac users. When you run Activity Monitor, does Zwift show up as “Zwift App Metal” or “Zwift App”? You might want to contact support.
Hallo Paul,
I noticed that Zwift now starts as “Zwift App Metal”. I don’t think that was the case before, but I’m not sure.
You might try moving aside the Zwift Metal App as mentioned in the post linked below. But you should make support aware of the problem so it gets fixed. Upgrading to Big Sur (11.6) would be another thing to try, but I’m a bit doubtful that will help since your OS already supports Metal.
I like the idea of automatic screen shots, but the one that gets taken at the end of an event is kind of useless. It would be nice if the game waited about 4-5 seconds after the completion of the event to take the snap.

This should be fixed in the next update.

Is there expected to be another update this month…or was ‘the new font’ the update for September? 
New font was 1.28.1.
Next update is 1.29. May be today.

Hi Youry, thank you so much for this workaround.
Do you know if there is a way to create these .wad and .ztx files with other fonts in them?

Great idea. Can’t wait to use Zapf Dingbats in Zwift!
Yes, this is possible. ZTX is private compressed picture format (probably not hacked yet), wad is private compressed archive format (I hacked it already). The simplest way is to repack ZTX (change symbols in-place), harder to change symbol dimensions (private font bin files need to be changed also). I don’t think I’m interested in this right now (lots of other things to do), but someday the Zwift programmers and designers will drive me to the point of no return and I’ll decompile ZwiftApp completely.

Windows version tgax and ztx formats are finally hacked - via standard dds. Now you can make your own texture patches (for programmers only): textures hacked · ursoft/zwift-offline@3508621 · GitHub
