+Subject: [PATCH] qwindow-compositor: compositor.cpp: fix display issue for
+ AM3/4
+
+On OpenGL ES 2 core implementation, only GL_CLAMP_TO_EDGE parameter is
+supported as wrap mode for NPOT (non power of two dimension) textures.
+However, the default parameter is GL_REPEAT.
+An extension OES_texture_npot adds the support of other GL_REPEAT
+and GL_MIRRORED_REPEAT to the wrap. However, many openGLES2 cores do
+not support this extension. Therefore, it is much safer to specify the
+wrap mode as GL_CLAMP_TO_EDGE.
+
+Note: This patch is for QT5.7.1 (morty) only because the qtwayland has been
+re-implemented at QT5.9.
