wpe_view_render_buffer: assertion 'WPE_IS_BUFFER(buffer)' failed
https://bugs.webkit.org/show_bug.cgi?id=298599
Reviewed by Carlos Garcia Campos.
An assertion failed in wpe_view_render_buffer() if the active web
process was switched before the previous rendering request wasn't
finished.
> ** (MiniBrowser:190744): CRITICAL **: 23:35:59.702: gboolean
wpe_view_render_buffer(WPEView*, WPEBuffer*, const WPERectangle*, guint,
GError**): assertion 'WPE_IS_BUFFER(buffer)' failed
In AcceleratedBackingStore class, if updateSurfaceID() is called
before renderPendingBuffer() is called, m_pendingBuffer is null in
renderPendingBuffer(). Check if m_pendingBuffer is null in the fence
monitor callback.
