Sure, here is the patch again with my real name.

From: Preston Carpenter <APragmaticPlace@gmail.com>

On Wayland compositors such as Sway and Way Cooler Xwayland windows will
be scaled twice if a TTY change occurs. This is due to sending the
output mode information twice, causing it to be applied twice to RandR.

This patch does not notify RandR if the size did not change, covering
the case where a TTY was suspended and then later resumed.
