This has been happening to me too, for the past few weeks. Roku, please fix this if you can!
Edit:
Looks like it may have something to do with the 13.0 update on May 14th, a bug that needs to be fixed (full numbered updates often bring bugs, hence the 0.x updates).
Hi @bach3,
Thanks for keeping the Roku Community posted!
We'd like to learn more about this, and thanks for sharing your experience. Could you share a photo of this issue? In addition, we'd like to know if a system restart helps or if it comes back after the reset.
Please also provide us with the details below once you see the issue.
We'll be anticipating your response.
Thanks,
Rey
Reset will fix it temporarily, and problem comes back within a few hours, across all apps and the Roku homepage (not just the MLB app shown in photo). It’s mostly missing letters, but some other UI elements have trouble loading sometimes too, like thumbnail previews for videos.
Thanks for reporting back along with the details.
Please be aware that I have passed along this to the appropriate Roku team for additional updates.
We'll make sure to keep this thread posted.
Best regards,
Rey
Here’s an example of block numbers when adjusting volume.
And this shows missing letters for’The Night Manager’ when attempting subtitles
