Background windows gets minimized when moving topmost window

[thiagomeireless]

I am not sure if this is a bug or a feature (that I would love to disable), but what happens is:

• I have an application open, e.g.: Firefox
• I open another application in the same space, that is set to float and sticky, e.g.: Finder
• I try to use the mouse_modifier + mouse_action1 (move) to move this float application and have 2 different outcomes depending if the application is focused or not:
  • If it's the currently focused window, I can move it as expected and nothing happens to the background applications
  • If it's NOT the currently focused window (e.g.: I clicked the background window), when I try to move it, all the background applications are minimized. <- this is what I want to fix/disable

Here's a video showing what happens:

I believe this is macOS system behaviour that interferes. What is the value of your mouse_modifier?
Try to set it to fn or ctrl and see if you can reproduce the issue.

Edit: Assuming this is system behaviour, there is likely a way to prevent it from triggering.

Hey @koekeishiya thanks for the quick reply! I never thought the mouse_modifier would be the problem, but it is.

This only happens when using the alt modifier. I tested with ctrl and cmd and both worked fine (didn't test with fn as I use an external keyboard with only 3 left modifiers)

Do you have any idea on how could I prevent it from triggering when using alt modifier?

It appears that yabai does not intercept the mouse-click for this action due to the level in which we observe events. I don't have a solution at the top of my head. See #1378 for history.

A fix to this particular issue is to insert ourselves at the HID level instead of AnnotatedSession, as was done originally; d4aa4c9 but that reverts some other fix.

I see. Sadly I don't have much C experience to try messing around with it, but as I can change the mouse_modifier to another key and it works fine, feel free to close the issue if you feel like it.

I would still love to be able to use the desired alt modifier, of course 😅

You can change this line https://github.com/koekeishiya/yabai/blob/master/src/mouse_handler.c#L286 from

mouse_state->handle = CGEventTapCreate(kCGAnnotatedSessionEventTap, kCGHeadInsertEventTap, kCGEventTapOptionDefault, mask, mouse_handler, mouse_state);

to

mouse_state->handle = CGEventTapCreate(kCGHIDEventTap, kCGHeadInsertEventTap, kCGEventTapOptionDefault, mask, mouse_handler, mouse_state);

and it will fix your problem, but it will revert other fix mentioned in #1378

Fixed on master.

Fixed in v7.0.0.

Hey @koekeishiya sorry for the ping on a closed issue, but I just upgrade and everything seems to be working well, except now the resize feature (mouse_modifier + mouse_action2) is not working. Trying with alt and cmd and problem persists.

Is there something I might be missing to configure in this new released version? No error logs:

❯ cat /tmp/yabai_thiago.out.log
yabai configuration loaded..
yabai configuration loaded..
yabai configuration loaded..

❯ cat /tmp/yabai_thiago.err.log
(empty)

asfd of course changing from AnnotatedSessionTap to HIDTap changes the timestep of reported events causing the resize throttling to change completely... without that code ever being touched.
