Marks in title bars are not updated when set on current container with children

[lbonn]

sway version 1.4-90d936d4 (Jun 13 2020, branch 'master')

Steps to reproduce:

• create a container with children (e.g: H[a b])
• prepare a command to set a mark sleep 2; swaymsg 'mark xx'
• focus on H[a b] before sleep finishes

H[a b] should then have "[xx]" in its title bar but it does not show until focus is moved to some other container.

An interesting variant (how I found this) is when I use rofi with some script to get a mark name as input and apply it on the currently focused container (H[a b]), the mark string appears but blinks at roughly 1Hz.

Maybe a damage tracking issue?

After more tests, it seems that the blinking coincides with my bar (swaybar) refreshing the time and the second bug does not occur when sway is run without a bar (refresh is immediate).

However, the first reproducers still occurs with no bar.

Very likely a damage tracking issue indeed.

Another clue: I can only reproduce the blinking using a layer shell menu (bemenu or rofi modified to use layer shell). If I use stock rofi using x11, I get no blink and immediate refresh.

Should be closed by #6844.

Just confirming that it's not happening anymore (sway version 1.10-dev-829c75b9 (Feb 27 2024, branch 'master'))
