Other display outputs work fine, but when i try to use the virgl paravirtualized output
-vga virtio \
-display gtk,gl=on \
the image gets mangled. I tried different resolutions with the other ok outputs but they all are mangled here. Curiously i also cannot seem to change the resolution within this here mode.
Running latest Haiku nightly and latest QEMU version.
If it’s of any help, a (not very pretty) output of devices section.
My host hardware is a intel igpu.
File QEMU issue under haikuports.

This is a Haiku bug, not a problem with QEMU. He should file a ticket with Haiku.
Change not the resolution but the color depth: 32 bpp works and is the only option that appears.
That worked. I changed it to 32 bit in the plain spice output, then booted back in virgil gl and the picture is OK and beautiful. 
I think 32 bit is the default bit depth setting in most cases?
If this is the case I will not bother anyone with filing a bug just for a special option (needed 16 bit it to make some programs draw faster but here it is faster anyway)
Yes sir, but as per above i don’t think i will.
Thank you all!
