supports EGL_KHR_surfaceless_context. If not supported, KWin tried to<br />
create a context through the Wayland API. Unfortunately on hwcomposer<br />
platform this results in a crash as libhybris only supports the init<br />
of EGLDisplay for one native platform.</p>
<p>This change tries to also use the SharingPlatformContext if there is<br />
an OpenGL context in general. It reuses the native EGLSurface created<br />
for the compositing scene and makes its own OpenGL context current on<br />
that surface, too. As KWin creates an FBO, it never renders to it, so<br />
it shouldn't matter at all.</p>
<p>In order to prevent EGL_BAD_MATCH errors when making Qt's OpenGL context<br />
current also the EGLConfig from the scene is used to create the context.</p></div></div><br /><div><strong>TEST PLAN</strong><div><p>Tested on Nexus5 with qtvirtualkeyboard in KWin</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>rKWIN KWin</div></div></div><br /><div><strong>BRANCH</strong><div><div>sharingplatform-hwcomposer</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D2231" rel="noreferrer">https://phabricator.kde.org/D2231</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>abstract_egl_backend.h<br />
