Windowed mode on Linux

[Nindaleth]

There are two bugs when running the game in a window on Linux:

• window title is "Tempest.Window"
• mouse cursor is always visible in the screen center and it oscillates around the center if moving the mouse (mouse control works normally otherwise)

[Dehela]

On this topic, running the game in window mode (with -window parameter), mouse movement is actually not captured. I can move mouse cursor around but in-game camera doesn't react to it at all. If I try to hold left mouse, it would start reacting to mouse movement but in different way (move camera to see your character at different angles).

[Nindaleth]

Interestingly, I don't suffer from that on X11. Are you running Wayland or X11? While I don't think it should matter (XWayland layer should handle it), your mouse movement issue sounds similar to what affects Steam Deck that runs the game in Gamescope Wayland compositor.

X11. Normal keyboard controls seem to be perfectly fine, only mouse is treated as if game window is not focused.

This is intentional. Windowed mode is designed for debugging. Basically I need a reproducible screenshoots between runs to debug shaders

window title is "Tempest.Window"

Window title is not implemented in engine :D Feel free to PR: something that work on Linux and does nothing on Mac/Windows is fine with me.

This seems like a bug: basically cursor in your case behaves, as in full-screen mode but remain visible. Maybe there is a issue with isFullscreen.

Might be good to have that note for window mode, so other players wouldn't be confused about it :)

I can't verify right now, but you're probably right as I still have that Steam Deck-related hackfix present even on my desktop :see_no_evil: I guess with that hackfix removed I'll have it same as does @Dehela

I have unrelated README.md PR in works, I'll add the note.

@Try are there any other debugging-only switches? I mean 100% useless to players - switches such as -g1 and -g2 or -dx12 (which I'll document too) are primarily debugging, but a user may still want to use them and profit from them.

Sounds like this issue could be closed at this point.

Added an engine ticket to implement setWindowTitle https://github.com/Try/Tempest/issues/40
