   Same issue here.

   Seems comming from #13728 which added some code to support terminal progress
   in emacs the $TERM usually point to "dumb", could it be related ?

   If the problem is the terminal progress, then it will be resolved by #13971. If you're looking for a workaround until the next point release, you can use -p no:terminalprogress.

   Although we should test that the TERM is not dumb as well, this way it won't have this issue even if explicitly enabled. I forgot about that, so thanks for reporting. I will add that to #13971.

   It is correct that TERM=dumb in EMACS comilation mode.

   I have tried with --color=yes and -p no:terminalprogress, I have the EMACS ansi-color plugin enabled in the compilation buffer. This makes it work.

   The terminal width is not interpreted correctly though, a window resize after pytest has been started fixes that.
   
   The initial terminal width was as wide as the final one, I made the window smaller end larger again.
   The terminal with issue is not new.
