Secondary windows are non-interactable

[Autumn :3]

Game Version​

v2026.7.4.4860, Linux native build

Operating System​

Linux, CachyOS, Kernel 7.1.3-2-cachyos, Mesa 26.1.4-1

What Happened​

Any secondary windows, which i classify as any window that detaches fully from the main window, (e.g. the ones that let you modify the properties of a part in the vehicle editor), do not react when anything is clicked, buttons do nothing, drop-downs do not drop-down, nothing happens.

What Was Expected​

Menu components in secondary windows should behave the same as they do in the main window.

Reproduction Steps​

1. Open KSA
2. Create a new vehicle
3. Spawn in any fuel tank part
4. Attempt to change the fuel type of the newly-created fuel tank (the secondary menu that you have to open to do this will be non-interactable)

Reproduction Rate​

Always.

Additional Info​

• Other Notes: I am on Wayland, if that makes any difference.

Are you in full screen or windowed? If youre in full screen try switching to windowed, and see if that fixes it

Issue still occurs in windowed

I wasn't having these issues on Windows on that same build so my guess is this one is a Linux-specific problem.

very likely, window problems have been a continuous thing with the Linux build

I did also have the same problem. But if you launch KSA with the `-fixed-viewport` flag, it prevents the windows from popping out, so that should no longer be a problem.
If you really want/need popped out windows, I have found that it works better when launching with `XDG_SESSION_TYPE=x11 linux-x64/KSA`. However there I had problems with the click position being offset relative to the window.
