2. Boot to desktop (may need ctrl-c  to skip some services at startup)
3. Select Info and watch for Workspace Manager info window to appear.
4. Move this window to the right - it corrupts!"""
additional = """Bug also exist if I boot qemu with  -g 1024x768x24

Moving window vertically (up/down) does not corrupt it
Moving any window around corrupt it.

Resizing and scrolling inside say Terminal emulators work.

There was 86Box issue around one FPU instruction that looked a bit like this, 
is there way to check fpu emulation?
