Infinite focus loop (and window blinking) when opening a second image in multi-window mode MWM

Environment/Versions

  • GIMP version: master
  • Package: self-build
  • Operating System: Linux / X11

Description of the bug

In Multi-Window mode, when opening a second image with shortcuts, I get some weird never-ending window blinking and the second image never appears.

Note: I have a fix for this bug, but since it was a complicated one and that I am unsure if my patch is ideal, I prefer to keep a trace so that someone can come back to it later if needed.

Reproduction

Is the bug reproducible? Always with some images (don't know why, the but is not image-type related)

Reproduction steps:

  1. Be in MWM
  2. Open a first image with Ctrl-1
  3. Open a second image with Ctrl-2 (note: the issue doesn't happen if I open the image through menus)

Expected result: a new image window appears with the second image and has focus flickering forever.

Actual result: the existing image window starts blinking and never stops blinking, the second image never appears.

You can actually break the never-ending focus flickering by breaking the focus, e.g. by clicking on a window, or by switching windows (e.g. alt-tab). This small screencast shows this issue happening with one image opened, then opening a second one with Ctrl-2, then the focus flicking happening only broken because I switched windows (only when I do this, the second window appeared, though it appeared below the existing window unexpectedly, which is why you don't see it in the screencast):

Additional information

After investigating in a debugger and adding a break to gimp_dock_window_image_changed, I realized that the issue seems to be that we get focus events "fighting" each other for the new (still not drawn) and the existing image window.

At first, we see some expected image change, to the newly created image, and therefore giving focus to the new display shell:
