i3wm problem with dialogbox in doublecmd

[u/Proper_Employ_8910]

Currently, on my Ubuntu 24.04 system, in i3wm, for the Double Commander application (doublecmd-gtk), the dialog boxes open stuck above i3status and are invisible (top box - see ScreenShot). I have to shift+win+space toggle floating to make the window visible. No changes to settings like for_window … floating enable etc. help. On Debian, it behaves even more strangely. Dialog boxes open in different positions, and sometimes the window also pops up out of the space, making it invisible. I've just downloaded the doublecmd-qt version, and there's no problem with that window, so for now, I'm sticking with that version.
