It’s not a common issue, as I haven’t seen anyone else complain about it, so it’s not likely to be a memory leak, but rather some interaction with your computer, most likely hardward or drivers.
Bug reports will definitely help them pinpoint the issue.
In the meantime, since it might be kinda related, maybe this also fixes your issue?
This was for those stuttering in the login screen, but it might also be kinda related? Worse case scenario is that it does nothing.
