On systems with old glibc, such mine with glibc-2.8, the following warning
is issued and is fixed easily by defining _GNU_SOURCE:
/home/me/SDL2-2.0.5/src/video/x11/SDL_x11modes.c: In function 'CalculateXRandRRefreshRate':
/home/me/SDL2-2.0.5/src/video/x11/SDL_x11modes.c:263: warning: implicit declaration of function 'round'
/home/me/SDL2-2.0.5/src/video/x11/SDL_x11modes.c:263: warning: incompatible implicit declaration of built-in function 'round'

I realized overnight that my patch probably broke text input events with UIM, and I confirmed that it does. Can't believe I overlooked that... I've been making stupid mistakes in these patches recently, sorry.
Anyway, *this* one seems to fix it properly. Knowing my luck it probably breaks something else.
Patch uses XkbFreeKeyboard to free the memory returned by XkbGetMap.
Earlier implementation called XkbFreeClientMap which frees all the maps
but not data->xkb structure itself, XkbFreeKeyboard will free maps and
the structure.

The patch makes StartTextInput/StopTextInput call Xutf8ResetIC ( https://www.x.org/releases/X11R7.5/doc/man/man3/XmbResetIC.3.html ) on the XIC of all SDL windows.
This fixes my use case in Quakespasm (Ubuntu 16.04, system keyboard layout set to German. Type the '^' dead key, which opens Quakespasm's developer console and calls SDL_StartTextInput, then press 'e'. I expect the dead key to be ignored.)
Also, here is a patch for sdl2's "checkkeys" for testing this: https://bugzilla-attachments.libsdl.org/attachment.cgi?id=2451

Just moved ibus direct call to SDL_IME_* related functions, and adds fcitx IME support (uses DBus, too),
enable with env: SDL_IM_MODULE=fcitx (ibus still the default one)

In SDL_x11modes.c the CalculateXRandRRefreshRate() function performs integer math on values that may return fractional results. This causes a value that would be calculated as 59.99972... to be returned as 59. In Linux the xrandr command returns 60Hz for this particular display mode yet SDL returns 59Hz.
I suggest this function be updated to correctly round the result of the calculation instead of truncating the result.
- Cache the _NET_FRAME_EXTENTS data locally, so we don't have to query
the X server for them (instead, we update our cached data when PropertyNotify
events alert us to a change).
- Use our cached extents for X11_GetWindowBordersSize(), so it's a fast call.
- Window position was meant to refer to the client area, not the window
decorations, so adjust appropriately when getting/setting the position.
This assert triggers when run under XMonad. It's safe to pass a zero here
anyhow, as this will still work "well enough" and the original
problem--GNOME printing a warning message--is still fixed because GNOME's
window manager gives us a chance to grab a non-zero user-time value before
this code is run.
(and thanks to Cengiz for many of the previous Unreal-related
patches! They were generically credited to Epic Games, but a large
amount of that work was his contribution.)
Fixes Bugzilla #3067.
This is for corner cases where a multi-window app is activated and wants to
make a decision about where focus should go.
This patch came from Unreal Engine 4's fork of SDL, compliments of Epic Games.
This lets windows know when they are dropping a mouse event because their
hit test reported something other than SDL_HITTEST_NORMAL. It lets them know
exactly where in the event queue this happened.

This is currently implemented for X11, Cocoa, Windows, and DirectFB.

This allows an app to know when a set of drops are coming in a grouping of
some sort (for example, a user selected multiple files and dropped them all
on the window with a single drag), and when that set is complete.
This also adds a window ID to the drop events, so the app can determine to
which window a given drop was delivered. For application-level drops (for
example, you launched an app by dropping a file on its icon), the window ID
will be zero.
