I used to think this was just an Eclipse bug, but it persist even after switching to IntelliJ Idea. I think this happens on other programs as well, but less frequently, and obviously matters far less.


Is there any workaround for this or do I just have to switch OS or something? I tried disabling compiz window fading but that didn't do any help.

OS: Ubuntu 15.10 WM: Whatever version of unity that ships with the above HW: Dell Latitude E7250 (non-touch, HD screen)

    I have the same problem on eclipse and ubuntu 16.04 did you find a solution? – Sebastien Aug 30 '16 at 14:58
  • Nope. It has just become less frequent since I updated to 16.04 but still happens time from time – Seppo420 Aug 30 '16 at 15:00
  • Well I felt that it became more frequent since 16.04 for me but I didn't do real statistics. – Sebastien Aug 30 '16 at 15:03
  • I often get this with LibreOffice, but also other programs. I wondered if it might be a video card / OpenGL driver issue, or somehing like that... Usually if I repeat what I was doing, it doesn't happen the second time. Very intermittent glitch, quite annoying though. – jdpipe Mar 30 '17 at 6:42

I have sometimes had a situation like this happen to me. Along with an equally irritating black dialog version.

I found a solution in the answer to this question: 13.10 - Black borders, black terminal

Which was to restart unity. Pop open a terminal window and:

setsid unity

After things settle down, most dialog issues generally seem to have sorted themselves out.

    Worked for me, however beware, IntelliJ will be terminated, along with presumably others. – Nick Jul 12 '17 at 20:10
