[SPZ2-6348] [Windows 11] When the game is in any long loading state, I can't switch to any other tab

[next surge]

These include but are not limited to;
loading a large save
quitting a large save
saving
enabling shape previews

During these times, pressing the windows key does open the taskbar and such, but switching to any tab doesn't work until shapez 2 has finished the load

Big savefiles have very long loading times and cause the game to freeze if it's minimized while loading
To Do • Priority: Medium • Fix: Post 1.0 • Game: 0.1.1

Large savegames with over 500k structures experience very long loading times, and the loading widget stops spinning during the process, which may lead the operator to believe the game has crashed. When the game is minimized while loading in borderless mode, a "stopped working" error message appears, though the game will eventually load if given enough time. Testing across multiple versions shows loading times have generally increased, with borderless mode being particularly affected when focu...

For bigger saves there is a delay before game is responsive on loading and then returning to the main menu
Done • Priority: Highest • Fix: 1.1 Release [1.1.0] • Resolution: Fix Verified

When loading larger savegames and returning to the main menu, the game becomes unresponsive for a noticeable delay. Repeating this cycle of starting a savegame and returning to the main menu causes progressively longer delays. The issue was caused by an async Unity operation traversing the entire scene hierarchy during screen transitions. The fix involved removing this operation, restoring behavior from earlier versions. The fix was verified as resolving the sluggishness in subsequent builds.

error when switching to other programs Low-end laptop
Done • Priority: Low • Fix: OLD Early Access • Resolution: Won't Fix

On low-end laptops, an error occurs when switching from shapez 2 to other programs. The issue is specific to devices with limited hardware capabilities. The error appears when the player alt-tabs or changes focus away from the game to another application. This affects the game's stability during multitasking. The report was marked as "won't fix" by the development team.

MacOS 14.2, Game unresponsive when switching tasks
Done • Priority: High • Fix: 4 - Early Access • Resolution: Done

On MacOS 14.2, shapez 2 becomes unresponsive when switching between applications. When the player switches away from the game to another task and then returns, shapez 2 hangs and must be force-quit. This happens almost immediately upon returning to the game window. The issue was caused by a Unity engine bug and has been reported by multiple users. It should be resolved after the Unity version downgrade.

There is a delay when unpausing after editing a large wire circuit
Done • Priority: Lowest • Fix: None • Resolution: Won't Fix

When unpausing the game after editing a large wire circuit, the game stops responding for a noticeable period. This can be reproduced by pausing, deleting a wire in a large circuit, and then unpausing. The expected behavior is that the game should not momentarily freeze when unpausing after editing a large wire circuit. This was closed as won't fix since there are calculations the game must run when unpaused, and the issue is considered minor and niche.

Ctrl+X just deletes instead of cutting if Shapez 2 autosaves while pressing the hotkey
Done • Priority: Medium • Fix: None • Resolution: Duplicate

The Ctrl+X keybinding only deletes structures instead of cutting them to the clipboard when an autosave occurs while the hotkey is being pressed. The issue happens because the cutting function does not complete properly when interrupted by the autosave process. The expected behavior is that Ctrl+X should cut the selected structures to allow pasting elsewhere, but instead it only removes them without saving to the clipboard. The user suggests blocking input during autosave to prevent this issu...
