WARNING:RENDER: Entire font glyph cache (1024 x 2048) is filled in a single frame 2988 ('1' 49). Consider increasing the cache for /assets/poppins/poppins_shadow.fontc
What does this warning mean?

Fonts with 0 in cache_width and cache_height are sometimes flickering in bundles… . This only appears to happen in bundles, not in builds triggered in editor.
When the issue occurs in a debug bundle, you get a message like:
```
WARNING:RENDER: Entire font glyph cache (1024 x 2048) is filled in a single frame 11374 (' ' 53412). Consider increasing the cache for <fontfile>
```
If you set the font cache_width and cache_height to 1024 x 2048 in an editor build, the issue does not appear. However, if you set it to a low value (e.g. 512 x 512) you do get the flickering and warning message.

Yes, thank you! The fonts are being used in labels and those labels are indeed flickering

Workaround is to manually set a large cache size.
