Expected Behavior

All letters in FreeType2 text should be rendered

Current Behavior

Some letters are skipped, see attached image

it should read МУРАКАМИ - Нулевой Километр. The issue is not caused by font, since displaying that string as static text works fine.

Steps to Reproduce

1. Create a FreeType text source
2. Configure it to read file named "record.txt"
3. Download record_archive.txt
4. Download random_record.sh.txt, rename to random_record.sh and run. It will create record.txt file and update it every 10 seconds.
5. After a few minutes the text in the source will not be rendered properly

Anything else we should know?

Notice: Seems to only affect text with Cyrillic letters (or maybe any non-Latin?). Attaching exported scene collection if that helps.

The exported scene collection seems to render fine for me.

Log shows that your source is running out of space to render glyph. You should probably reduce the pt size of your source's font if you will be rendering text in many different scripts, once we run out of space the cache will only be rebuilt by changing font or aa settings and new glyphs will not be rendered.
