I tried running under Wayland again and i can't reproduce this - although i did manage to trigger some strange behaviour and breakage after changing to random resolutions, maximizing, minimizing, and doing various things.

Is this a full-desktop window like you get when you click "fullscreen", or just a maximized window? What i mean is, are there any bars or docks reducing the screen area, or is it taking up the whole display?

I did sometimes manage to get it into a state where the wrong resolution was being used by the game, and the remainder of the space was black. However even in this case it was mapping the cursor correctly.

For reference i'm running SDL version 2.0.20. There were many Wayland-related changes in SDL recently, but as far as i'm aware it's still not considered stable on Wayland even in the latest version.

Graphics hardware may also be an important factor. Nvidia at least still don't fully support Wayland.

Maximized desktop window, but I can reproduce the same issue when I switch from maximized window to fullscreen.

I have Intel GPU.

It's not clear to me what the image is supposed to be illustrating. Is it the case that a click at the position where the mouse cursor is registers as a click on the General tab?

Yes

I suppose you don't get the mis-alignment on X11? At a glance this looks similar to what I reported in #5518 (comment) except I don't use Wayland.

No, it works fine on X11, on Wayland it is broken.

I'm closing this bug. I retested on 314f6f7 and I cannot reproduce this issue. I think this could be caused by some KDE/Wayland.
