Created attachment 150338 [details] An ODT document for testing bug. there are 4 sentence in this document. First sentence pure Persian with no problem and lag when I wrote it. Second one is in Persian with Persian numbers so was laggy as I was writing. Third one is mixed of English and Persian (فارسی) and was laggy. Last one pure English so no problem as expected.
Does it work if you disable OpenGl ? -> https://wiki.documentfoundation.org/OpenGL I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the issue is still present
Unfortunately no. even with OpenGL disabled problem is still there.
Homayoon did not actually have OpenGL enabled as seen from the Help - About text. I think we should remove the question as people many times do not understand what it means. Homayoon: how does the lagginess manifest? I did not experience anything weird with your file and doing some inputting of text.
