Using KMS/DRM driver from WIP SDL2.0.6 on Linux/ARM SoC RockChip RK3328 (ARM Mali 450 MP2 GPU).
The current code is using GBM_BO_FORMAT_XRGB8888 as GBM buffer format specifier.
The Mali driver (it has been confirmed some other vendor implementations too) expects GBM_FORMAT_XRGB8888.
The Mesa implementation is actually handling both values as the same, but it's not implemented like this into every gbm.h vendor header.
https://github.com/ideak/mesa/blob/master/src/gbm/backends/dri/gbm_dri.c
So with stock SDL2 on my card (Mali vendor implementation), it does not work, eglCreateWindowSurface fails, and gbm_is_format_supported fails too (with the BO variant).
It runs fine with GBM_FORMAT_XRGB8888.
Here is a link of the gbm.h from Mali user-space driver :
https://github.com/rockchip-linux/libmali/blob/rockchip/include/gbm.h
This is necessary because we need to see if GLES compat extensions exist.
All of this code (including ShouldUseTextureFramebuffer()) should be
revisited after 2.0.6 ships; ideally we don't make throwaway contexts if
we can avoid it...but maybe we can't. I hear Vulkan is pretty cool.
Fixes Bugzilla #3725.

Using the pre-built x86 devel libs from here:
https://www.libsdl.org/release/SDL2-devel-2.0.5-VC.zip
If I have:
SDL_GL_SetAttribute(SDL_GL_CONTEXT_PROFILE_MASK, SDL_GL_CONTEXT_PROFILE_ES);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 2);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 0);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_FLAGS, SDL_GL_CONTEXT_DEBUG_FLAG);
and I'm using ANGLE/(a GL driver that doesn't provide an ES2 context) such that SDL_EGL_CreateContext is called by SDL_GL_CreateContext, I get the error "Could not create EGL context (context attributes are not supported)" and no context is created.
Looking at the code in SDL_EGL_CreateContext - if gl_config.flags is non-zero, it looks like the code in the section guarded with "#ifdef EGL_KHR_create_context" should be executed - but it apparently isn't.
Is it possible this section hasn't been compiled into the pre-built libraries? If I build SDL2.dll myself using the Visual C++ solution (VS2015 Community Update 3) then the call succeeds as I expect

When exiting a "fullscreen space" on OS X, windows don't go to their defined "windowed mode size", but go back to their previous size.
Steps to reproduce:
1. Create a windowed mode SDL window
2. Toggle it to fullscreen with the SDL_WINDOW_FULLSCREEN_DESKTOP flag
3. While in fullscreen, change the windowed mode size using SDL_SetWindowSize
4. Toggle the window back to windowed mode
Expected result:
- The window has the size specified during step 3.
Actual result:
- The window has the size specified when creating the window in step 1.
Attached is a minimal reproduction test case.
The attached test case works as expected on X11 and Windows.

fix windows build after revision 11382: commit 2026e42e377a renamed
_SDL_msctf_h to SDL_msctf_h_ . SDL_windowskeyboard.c relies on that
macro, so update it accordingly.

Since the Vulkan merge, building against a Mac OS X SDM older than
10.11 fails in SDL_cocoametalview.m because Metal.framework is not
present. There is no conditional compiling in SDL_cocoametalview.m
either, so --disable-video-vulkan doesn't help with anything. (The
configury doesn't check darwin for x86_64 either, but it's another
story.)
I cross-build against 10.8 SDK on linux using clang-3.4.2 and this
is a problem for me. Will this be fixed?

The default path used by directfb for libGL is different than the default path used by x11 in SDL2:
./src/video/directfb/SDL_DirectFB_opengl.c:
path = "libGL.so";
./src/video/x11/SDL_x11opengl.c:
#define DEFAULT_OPENGL "libGL.so.1"
On at least one distro (Alpine Linux), libGL.so is not created (or more accurately the symlink to libGL.so.1 is not created). For consistency, the 'path' variable in SDL_DirectFB_opengl.c should patch the DEFAULT_OPENGL in SDL_x11opengl.c ("libGL.so.1")
Error message was:

We would like to add a switch (define) that allows us to compile Angle statically with SDL. That is, getting rid of the OpenGL DLL. Usually you need OpenGL to be loaded dynamically as DLL because implementation is provided by the system but no need with Angle.
Only 2 files need modification and it shouldn't affect current behaivor:
include/SDL_egl.h and src/video/SDL_egl.c, as in here
https://github.com/native-toolkit/sdl/pull/10/files
The flag name could be SDL_VIDEO_STATIC_ANGLE (instead of NATIVE_TOOLKIT_STATIC_ANGLE) as discussed here https://github.com/native-toolkit/sdl/pull/10
We have tested this with both Windows and UWP, using NME engine (https://github.com/haxenme/nme).

This fixes a strange corner case (notes appended below), and should be
safe to do anyhow.
Fixes Bugzilla #3674.
"I did more tests.
It appears the bug only happens if there is
another window on the screen that has "always
on top" property. For me it is xawtv - it is
always opened in a screen corner. Closing
xawtv or removing "always on top" property
from it makes the problem to go away.
Plus, it doesn't appear like the buttons are
not delivered at all. It appears that instead
the button presses are delivered on some mouse
positions, but not delivered when you move the
mouse to other part of the window... So this is
really weird and is likely somewhere deep in the
Xorg.
Maybe somehow it happens that the cursor is
actually above the xawtv window, but, because
my app uses grab, it is not visible there, and
in that case the events are not delivered to
my app?
But with my patch the button events are
always delivered flawlessly, it seems.
Hmm, and that indeed seems to explain my problem:
if the mask is set properly and my app uses
grab, then, even if the mouse is above some
other window, the events would still be delivered
to the grabbing app, which is what actually wanted
because my app uses relative mouse mode, so it
doesn't know the pointer can cross some other window
(my app draws the pointer itself).
So my current theory is that my patch only enforces
the mouse grab, which otherwise can be tricked by
some other window preventing the button events
delivery (but motion events are still delivered
via xinput2, which makes it all look very obscure)."
This patch was originally written by Marc Di Luzio for glX and enhanced by
Maximilian Malek for WGL, etc. Thanks to both of you!

With the system dialog font set to Arial or Tahoma or another variable-width font, everything works just as expected. When using a fixed-width font, like Courier or DejaVu Sans Mono, the text gets cut off. Example screenshots attached.

I implemented precise scrolling events. I have been through all the folders in /src/video/[platform] to implement where possible. This works on OS X, but I can't speak for others. Build farm will figure that out, I guess. I think this patch should introduce precise scrolling on OS X, Wayland, Mir, Windows, Android, Nacl, Windows RT.
The way I provide precise scrolling events is by adding two float fields to the SDL_MouseWheelScrollEvent datastructure, called "preciseX" and "preciseY". The old integer fields "x" and "y" are still present. The idea is that every platform specific code normalises the scroll amounts and forwards them to the SDL_SendMouseWheel function. It is this function that will now accumulate these (using a static variable, as I have seen how it was implemented in the Windows specific code) and once we hit a unit size, set the traditional integer "x" and "y" fields.
I believe this is pretty solid way of doing it, although I'm not the expert here.
There is also a fix in the patch for a typo recently introduced, that might need to be taken away by the time anybody merges this in. There is also a file in Nacl which I have stripped a horrible amount of trailing whitespaces. (Leave that part out if you want).
