In the terminal window, sometimes after pressing a key the windows "freezes" for a few seconds. I can continue typing afterwards, but after a few seconds-minute it happens again.

The freeze happens ONLY after I type.

I am using Ubuntu 18.04 with Unity+compiz (don't know if it is related, because it didn't happen right after the installation of the OS). Also running on VMWare.

output of "lspci -nnk | grep -i vga -A3"

00:0f.0 VGA compatible controller [0300]: VMware SVGA II Adapter [15ad:0405]
        Subsystem: VMware SVGA II Adapter [15ad:0405]
        Kernel driver in use: vmwgfx
        Kernel modules: vmwgfx

Happens only in Unity Desktop + comiz is disabled


  • what does the journal say around the time of the incident? I would try running jouralctl -f and check what it says when the window freezes – j-money Jul 15 '18 at 15:26

    @TCS I think (I have been wrong before though...) that context mismatch.... is due to the use of video acceleration, you may try disabling it to see if that fixes the problem – j-money Jul 16 '18 at 6:17
  • @justinbenge - that worked! write an answer :-) – TCS Jul 16 '18 at 17:36

compiz[2222]: context mismatch is due to a use of video acceleration, so usually disabling it should fix the problem :)
