Brief freeze in Gnome dialogs in 19.04

  • 772

After upgrading to Ubuntu 19.04, I have noticed a visible freeze of a couple of seconds whenever I click a button of a Gnome dialog window. One case when it appears is the screen unlock window, but even the "open file" dialog in most applications gives the same behaviour.

Journalctl displays some error messages that appear to be related [EDIT: the messages were a red herring apparently; they do not appear at the same time as the bug happens.]

Any ideas as to what could be causing it? Is it a known problem? Any experiment

    I turned out, that the freezes are a product of a bug in gnome-shell-extension-desktop-icons is.

    @Federico Poloni found his own workaround.

    Go fishing is a good thing :D

  2. Do you use an Nvidia Optimus with modeset enabled? In my case setting modeset=1 for nvidia_drm module causes intermittent freezes. You can try disabling it.
