Same issue in both branches.

Mali system crash on frameloop termination

On Mali Midgard T860 platforms (RK3399) terminating the frameloop produces a what appears to be a kernel crash, followed by a system restart.

egl version, vendor, extensions:
        1.4 Midgard-"r22p0-01rel0"
        ARM
        ...

gl version, vendor, renderer, glsl version, extensions:
        OpenGL ES 3.1 v1.r22p0-01rel0.e7480ede12f1b3abcc83236b8600f7b3
        ARM
        Mali-T860
        OpenGL ES GLSL ES 3.10

Scenarios that result in the crash:

• Termination of wl_display_dispatch frame loop
• Change of window foreground status -- e.g. switching to another app.

Scenarios that don't result in the crash:

• After the last valid frame, app stays on foreground and redraw continues to invalidate the wayland surface, but without invoking app's render_frame, so that last two frames alternate ad infinitum.
• No wl_surface is committed and no wl_display_dispatch is invoked.

Behaviour reproducible on R69-stable.

Can't get this working in newer ChromeOS

On M86:

sudo ./test_egl_sphere 
No protocol specified
No protocol specified
No protocol specified
No protocol specified
eglInitialize() failed
EGL error: EGL_NOT_INITIALIZED
Error initializing GLES

(also libwayland got replaced by mesa + wayland in chromebrew so the docs need updating.)

R70 performance issues

1. The new alpha-blended + blurred shelf overlay in R70 kills the performance of underlying apps when blended on top of a 60fsp GLES app. R70 is the first revision where the shelf overlay is not just alpha-blended but is also blurred, so apparently this takes plenty of resources from the underlying app. As a workaround hide the shelf overlay when running 60fps GLES apps.

2. The fence-sync scheme on redraw performs poorly under R70, resulting in frequent framerate stuttering; scheme disabled as of commit 55b1481.

Fatal build error

Not sure if this is just me, but the header file <bits/c++config.h> is missing. Help?
