Right to left text in chat

I am on a regular zoom call where the chat text is in Hebrew which is written from right to left. Two weeks ago everything was fine but today I found that the last letter of the last word, i.e. on the extreme left side of the chat screen, was only displaying the right half of the letter and not the whole letter. The whole letter was there because I could copy and paste it, but the whole letter did not display. I was not entering anything in the chat, just reading it.

Any clues as to how to overcome this problem?
