🐞 window jump when dragging on the secondary (external) display

[Ender-Wang]

Bug Description

I have seen a weird behavior when I drag app windows when I am connected to a second display.
When I drag a window on the external display(secondary display) around (drag it within the screen, not to the main display), the app jumps to the bottom of the main screen (mac display), I am not sure if it's a bug related to Loop or macOS 15.7. Since Loop is the only window manager app I have on this mac, here I am. Noticed this recently when I work on the second display, multiple times a day.

Steps To Reproduce

• Connect mac to a second display, mac screen set to main screen,
• drag a window on the secondary display

Expected Behavior

The app should not jump to the other display.

Actual Behavior

App window jumps.

Can you try updating to the latest development version (1.4.0) to see if this issue persists? You can enable the development version in Loop's "About" tab.

Ok, I will report back in a few days. Thanks.

It's much less frequent, but worse when it happens. Happened once in the morning, but the same jump happens, the window glitches a bit, then jumps to the other screen. I will close Loop for a while, just to eliminate its system bug.

Edit:
Do you recommend disabling those while using Loop? I just disabled those. Maybe there's some sort of conflicts going on with these enabled.

It is possible that this is the cause. I will reproduce the bug in the next few days and can tell you more about it then. Thank you for creating the issue

Do you have "use macOS window manager when available" enabled?

Nope, it's always off.

In case settings matter, this is mine.

@Ender-Wang one more test, could you try running a version of Loop before 1.3.0, like 1.2.0, to check if the bug existed back then? If you already had that version installed a few months ago, it might help confirm whether this is something new in macOS 15.7 that’s causing issues with Loop.

@MrKai77 I have had this issue before macOS 15.7, on 15.6, etc, but I will give it a try with v1.2. Will report back soon.

@MrKai77 I've been using it for a few days, and I haven't encountered any issues with v1.2. No glitches at all. macOS 15.7.1, a M3 family mac.
