NetBSD empusa 7.99.5 NetBSD 7.99.5 (ODROID-C1) #466: Fri Apr 3 14:43:09 ADT 2015 Jared@Jared-PC:/cygdrive/d/netbsd/src/sys/arch/evbarm/compile/obj/ODROID-C1 evbarm
>Description:
Not sure if this is an xsrc or pkg bug.
I'm seeing corrupt pixbufs in Midori etc on ODROID-C1 when running with a 24-bpp display. The problem disappears if I run at a different display depth.
It looks strangely exactly like the display corruption I've seen on i965 with drmkms. I can reproduce it easily with the "gtk-demo" app. Here is the expected result:

Here is the result of running the same test with a 24bpp framebuffer:

>How-To-Repeat:
Using a 24-bpp framebuffer in X, run "gtk-demo" and double-click the "Pixbufs" test.
