Sway Version:

• sway version 1.9

Debug Log:

• Sway: https://tpaste.us/D7Ko
• Affected client's WAYLAND_DEBUG: https://tpaste.us/b1rL

Configuration File:

• I think you only need for_window [app_id="org.foo.bar"] floating enable line in a configuration

Description:

• Sway sometimes handles window resizes incorrectly and fails to send appropriate event to involved clients.
• Steps to reproduce:
  1. Grab tinywl sources from wlroots-0.18.0;
  2. Apply the following patch to set compositor's app_id: https://tpaste.us/BJYy. Note that app_id is being set after output initialization;
  3. Run patched tinywl in sway from terminal window;
  4. Observe terminal window being smaller than its container so you can see sway background through it.
