for the same XDisplay as the X11 pixmap. This means if we created an<br />
EGLDisplay for a GBM device, we are not allowed to load a texture from<br />
the X11 pixmap and can result in a crash in the driver.</p>
<p>Similar in the nested X11 setup the EGLDisplay is created for the<br />
rendering window, but the X11 pixmaps are from the Xwayland server KWin<br />
started. They don't belong to the same windowing system.</p>
<p>This change addresses this problem by moving the loading of X11 pixmaps<br />
from AbstractEglTexture to EglTexture of the EglOnX11Backend. Thus for<br />
any usage on a non X11 platform we cannot hit the code path any more.<br />
In addition the nested X11 platform can indicate that it doesn't support<br />
it and thus also doesn't go through the code path.</p></div></div><br /><div><strong>TEST PLAN</strong><div><p>Tested standalone and nested X11 platform</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>rKWIN KWin</div></div></div><br /><div><strong>BRANCH</strong><div><div>texture-from-pixmap-x11-only</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D1857" rel="noreferrer">https://phabricator.kde.org/D1857</a></div></div><br /><div><strong>AFFECTED FILES</strong><div><div>abstract_egl_backend.cpp<br />
