[virglrenderer-devel] Anyone see black screen when refreshing qemu window?

[Lepton Wu]

Hi,

Here is a bug I met when running virlgl + qemu with my guest (Chrome OS).
I've put a video here to show what I mean: https://youtu.be/yG-BbWHOwG4

As you can see, when I moved around another application window, qemu
will show black screen
sometimes. This only happen when  running qemu with virgl option.
Actually this could be a bug
in qemu side, but just wondering, is this a known issue happening to
everybody or just something
specific to my setup.

Thanks!
