Hello!
Will try this in Unity 2022 soon, but I've been doing a lot of stability updates to shaders that will hopefully be published soon. I was experiencing text overlapping like that at one point, but have not been able to reproduce it since... I feel that this might be an issue more related to the problems with event-based things being broken in newer unity versions rather than shader issues, and I'm still working on those! If you send me an email through my website I can send you a patch of how STM is currently, but I'm not completely sure it will solve this issue just yet.
Thank you so much for your patience!
