shell=mtm #904

when the shell=mtm in foot.ini, the prompt starts at the top of the terminal for a split second and then it gets moved down in the terminal. this issue does not occur when you type mtm into the terminal, only when mtm is the shell in foot.ini

steps to reproduce: install mtm, set shell in foot.ini to mtm

The window resize that happens shortly after foot starts (see #453) has been known to trigger some issues before, but I've never seen a case yet where the child program wasn't the likely cause. The window resize can lead to some "flickering" but it shouldn't cause the prompt to be incorrectly positioned (or not printed at all; which is another bug I've seen with mtm).

Some people have mentioned that adding a small delay (e.g. foot sh -c 'sleep 0.1; mtm') usually makes the problem go away.

Yeah, it's only likely to occur when foot execs a program shortly after being started itself (i.e. with foot mtm or foot -o shell=mtm). If you type a command into an already running shell, the initial window resize already happened long ago.

Closing as a duplicate of #453
