848	Sticking PS/2 mouse in Qemu, unless full-screen	Jiri Svoboda		"PS/2 mouse in Qemu (i.e. through i8042) tends to stick after moving some distance in Qemu. The problem can be seen on ia32, amd64 or even sparc64/ultra (because Qemu sun4u machine is a PC hybrid with i8042). The problem is normally not seen when running amd64/ia32 with ew.py, because in that case USB tablet is used.

I originally thought this was a bug in Qemu, because it goes away if you switch Qemu to full-screen mode. However...

the problem is reproduced with:
  * HelenOS 0.11.2 / Qemu 5.2.0 .. YES
  * HelenOS 0.11.2 without Window system / Qemu 5.2.0 .. YES
  * HelenOS 0.6.0 / Qemu 5.2.0 .. YES
  * HelenOS 0.5.0 / Qemu 5.2.0 .. NO(!)
  * Windows 3.11 / Qemu 5.2.0 .. NO
  * Windows XP SP2 / Qemu 5.2.0 .. NO
  * SkyOS 5 beta 6947 / Qemu 5.2.0 .. YES

Note that Compositor was introduced in HelenOS 0.6.0 and the problem does not occur with the previous graphical console. Also note that the same problem occurs with SkyOS. It also happens with current HelenOS even with Window System disabled.
