+qemu-system-aarch64 shows black framebuffer window on minimal bare metal example on SDL but not on VNC
+
+QEMU v2.12.0, Ubuntu 18.04 host.
+
+Build QEMU and the bare metal image exactly as described at: https://raspberrypi.stackexchange.com/revisions/85135/4 with:
+
+Then cd into example 09_framebuffer.
+
+Now if I do:
+
+../../qemu/aarch64-softmmu/qemu-system-aarch64 -M raspi3 -kernel kernel8.img -serial stdio
+
+the SDL window shows up black.
+
+However, if I use VNC:
+
+../../qemu/aarch64-softmmu/qemu-system-aarch64 -M raspi3 -kernel kernel8.img -serial stdio -vnc :1
+vinagre :5901
+
+an image of Homer Simpson appears as expected.
+
+Therefore, I think this must be a QEMU / SDL bug instead of the repository, since we get different behaviors with `-vnc` and with SDL.
+
+Things that work:

+- the UART examples on the image repo: https://github.com/bztsrc/raspi3-tutorial/tree/9e5611a624b3037788d5b29d951304938bff13ea/05_uart0

+Works for me with both the GTK display and '-display sdl' with current head-of-git QEMU...
+
+
+Hi; I'm moving this bug to 'incomplete', because I was never able to repro it -- gtk and sdl displays both worked for me.
