The pixel format was hardcoded to PIXMAN_a8r8g8b8. All other renderer->read_pixels() calls in weston use dynamic format selection via the compositor->read_format instead. The problem was spotted on the ARM devices with Mali-400 GPU. The visual effect of the problem was black screen on the remote display, when using screen-share with the VNC or RDP backends.
