I just upgraded from xubuntu 16.04 to 18.04.1.

Now I can't see some buttons and sliders. Menu configuration option buttons are not visible. Slider for volume control for pulseaudio is not visible. On the whisker menu, I see circles covering the names of categories. Terminal window pull-down menu items have no spaces but they are clickable and selecting items from the pull-down menu work.

Applications seem to work for the most part, but not being able to control the volume and not seeing the categories on the whisker menu are super annoying. I don't know what else may be broken. Can someone point me in the right direction? Is this a matter of destroying/modifying some dot files for configuration? I removed the whisker rc file, but the problem persists.

  • Here are some screenshots that show part of the issue: imgur.com/a/Yr51Mky – Larry Jun 21 at 18:09
  • Have you installed any themes? If so, change to the default theme and recheck. – heynnema Jun 21 at 18:11
  • changing themes don't seem to help. I added another picture to the link above showing the whisker menu. correction to above, I'm on 18.04.2 – Larry Jun 21 at 18:31

Turns out that the gtk theme I was using was no longer being developed and support ended on 16.04. I loaded a current Adapta gtk theme and all of the issues went away. Thank you @heynnema for the suggestion. Pointed me in the right direction :)
