When I startup qemu, it sometimes shrinks to a very small size. This can be countered by making it full-screen or resizing it, but both of those are not very practical when I'm just loading it up to test a quick change, then unloading, making another, loading again, etc.

Does anyone know how to stop this?

I'm using kde 4.7.4 on ubuntu 11.10 with the default kubuntu packages installed.
It didn't happen when I was using debian 6.0 on the same machine with some sort of kde 4.

Thank you.

It's a window manager issue, but it's mostly qemu's fault.

No real fixes, but I do know of two workarounds:

- You can try to run a different window manager, but that's... obviously not an ideal solution (xfwm4, for example, does not have the problem; compiz and kwin do these days - seems the more-mature OpenGL compositors have this in common).

- You can use the key binding ctrl+alt+u to make QEMU resize to the "proper" size for the current virtual display.

Thanks!

I have a similar problem using Ubuntu 12.04. It starts normally, then starts randomly changing size and/or position about 3 times a second for 4-5 seconds, until it returns to (near) normal and (near) original position. I always figured it was something I was doing wrong, and never worried about it.
