When using emulated display modes, the output size is often larger than the drawable buffer. As the surface damage region is automatically calculated from the smaller drawable buffer size, the damage region needs to be manually set to cover the entire viewport region or visual repaint artifacts can result.
I kind of thought it'd be nice to have it in the center, but this is an issue
for applications that still assume global mouse and window positions are
accessible. For example, this fixes cursor offset issues in UE5.
It's possible that an external component (probably a GL/VK context) committed, so we need to cover our bases and detach in both HideWindow and ShowWindow.
Fixes a crash in UE5 editor's pop-ups.
Partially fixes the mouse cursor in UE5 editor. Imperfect because UE5 uses window position and global mouse state to get position, but of course we don't have global mouse and this is just to get the right display index so this still fails overall. We really need to make global mouse support a feature query...
So if Gnome/KDE/etc have a keyboard shortcut or titlebar decoration to
make any window go fullscreen (with the _NET_WM_FULLSCREEN flag on the
_NET_WM_STATE property), we update the SDL window flag.
Fixes#5390.
This makes sure the window doesn't have outdated values if you try to access
them (or call something that does, like SDL_SetWindowMinimumSize).
Fixes#5233.
On Wine, when a window is programmatically minimized in response
to losing focus, we receive a WM_ACTIVATE for the deactivation,
but GetForegroundWindow still indicates that our window is focused.
This causes an incorrect SDL_WINDOWEVENT_FOCUS_GAINED.
This is probably a Wine bug, but it may take a while to fix and
then for the fix to make its way to users.
libGL.so may register callbacks that can be invoked upon XCloseDisplay().
If XCloseDisplay() is called after libGL.so is unloaded, the callback pointer
will point at freed memory and invoking it will crash.
The texture framebuffer check optimized out in f37e4a9 was causing libGL.so to
never be unloaded as a side-effect. Skipping it exposed this bug by allowing
libGL.so to actually unload.
We were returning the report size from HIDAPI_DriverPS5_RumbleJoystick() rather
than 0 upon success, causing SDL_JoystickRumble() (and callers) to think that
rumbling failed.
This didn't cause major problems until 1868c5b, when it started preventing
rumble state from being persisted in the joystick core, even though it was
successfully sent to the hardware.
This led to all sorts of strangeness, including broken rumble duration and
attempts to stop rumble being discarded.
The functions can go south if other operations are in progress, like
X11_SetWindowBordered, which might be doing something traumatic behind the
scenes of the window manager.
We can't make these tasks totally synchronous, which would fix the problem,
because not only can the window manager block however long it wants, it might
also decide to deny our requests without any notification, so we'd be waiting
forever for a window change that isn't coming. :(
Fixes#5274.
Use viewports for non-fullscreen windows when the desktop uses fractional scaling and the window is flagged as DPI-aware to provide a backbuffer mapped as close to 1:1 output as possible. In the cases of odd window sizes the backbuffer may be a pixel off of scaling perfectly into the window size due to its scaled size being rounded off, but a minute amount of scaling during output is likely preferable to the large amounts of overdraw needed with integer scaled buffers.
Expose as many emulated display modes as possible. They will currently display stretched to the display's native desktop aspect, but if an application requires a hardcoded resolution, it will work at minimum.
Aside from the change in the emulated display mode list, the Wayland event handling code had to be updated to support separate scaling for the x and y axes, as square pixels are no longer guaranteed.
Wayland doesn't support mode switching, however Wayland compositors can support the wp_viewporter protocol, which allows for the mapping of arbitrarily sized buffer regions to output surfaces. Use this functionality, when available, for fullscreen output when using non-native display modes and/or when dealing with scaled desktops, which can incur significant overdraw without this extension.
This also allows for the exposure of arbitrarily sized, emulated display modes, which can be useful for legacy compatability.
1. Mod index values are (mostly) constant, so can be done with xkb_state_new
2. Mods can change without the group changing, avoid remap events if possible
Lastly, as a bonus, I added braces to the locale check, because I was nearby.
When using shared linking (linking in the normal way with
-lwayland-client) rather than loading Wayland libraries dynamically at
runtime, listing symbols that don't exist in the current version results
in a build failure. We don't actually call wl_proxy_marshal_flags() or
wl_proxy_marshal_array_flags() directly; the reason we need them is
that they're called by the code generated by wayland-scanner >= 1.20.
If we're building against an older Wayland library, then we'll have its
corresponding version of wayland-scanner (mismatched versions are not
supported), so we won't need those two symbols, and can avoid generating
a dependency on them.
Conversely, if we're building against a newer Wayland library, the
generated code will call them unconditionally, so we cannot treat them as
optional and gracefully fall back: that would result in a crash. Instead,
treat them as a mandatory part of the Wayland library, so that if they
are not found at runtime, we can fall back to X11 without crashing.
libwayland 1.18 is in several LTS distributions (Ubuntu 20.04,
Debian 11, RHEL 8) so avoiding a hard dependency on 1.20 is quite
useful.

Using wl-output to get the desktop display dimensions and dividing by the integer scale factor will not return the correct result when using a desktop with fractional scaling (e.g. a 3840x2160 display at 150% will incorrectly report the scaled desktop area as 1920x1080 instead of 2560x1440). Use the xdg-output protocol, if available, to retrieve the correct desktop dimensions and offset.
Versions 1 through 3 of the protocol are supported.
- which also enable/disable the orientation lock status.
This is only provided when the window is not SDL_WINDOW_FULLSCREEN (see SDL_video.c).
Final orientation also depends on SDL_HINT_ORIENTATIONS.
The Java code needs the native functions to be implemented, even if
they're not surfaced via the C API, therefore, a stub version of
functions were made only to the purpose of "fill the gaps" when
SDL_HIDAPI_DISABLED set to 1.
if SDL_EnumUnixAudioDevices() fails to find any devices,
set an error message on the exit path. Without this,
SDL_Init() could fail without any message available
in SDL_GetError().
This isn't obvious, but makes sense when thinking about how games actually use it. This is also in line with how Windows mouse relative mode is implemented.
