Hi; sorry for the delay in testing this. I've just tried your attached test image with current head of git QEMU (commit 0e87fdc966d05f4e5ad86, which is the 2.12.0-rc2 release candidate), and it gives me a correct display both with and without -icount 2. So I think we've fixed this bug, probably with the combination of commits 0790f86861079b19 and 87f963be66a3245, or possibly a75a52d62418da. thanks -- PMM
