1.10-rc3 output toggling leads to the monitor modeset when switching tty with multiple sway sessions

[malvery]

• Sway Version:

  • sway version 1.10-rc3
  • wlroots 0.18.1

• Debug Log:
  sway.log

• Configuration File:

  • default configuration

• Description:
  Steps to reproduce:

  • Run sway session 1 on tty 1 and run sway session 2 on tty 2, set same monitor modesets.
  • Switch tty's => switching between tty's is instantaneous
  • Run swaymsg "output * disable" && sleep 2 && swaymsg "output * enable" on any tty, and try to switch tty's again => every switching leads to set modeset again (~3s for my example)

But, I cannot reproduce it on the master sway/wlroots branch.
