How to get rid of buggy IntelliJ IDEA dialog that won't go away?

  • 772

This is a bug I run into every couple of days, with IntelliJ IDEA's "Go to Class..." (or "Go to File...") dialog.

Usually it closes normally (when a class is selected or Esc pressed), but sometimes the popup is left behind, in the middle of the screen, on top of everything else. Even when I quit (or kill) IDEA completely, it stays. Example of what it looks like:

enter image description here

Only way I've found to get rid of it is logging out completely and then back in (i.e. restart X / GNOME). But having to do that is very annoying, as it can take 10 minutes or whatever to save (and re-setup afterwards) everything I have open.

Is there any other way to get rid of the buggy popup dialog, while remaining logged in? (Such as restarting some GNOME or X service / process.)

Using Ubuntu 11.04 and GNOME (not Unity).

IntelliJ IDEA ultimate edition 10.5, running on Sun's JDK 1.6.0_26 (i.e. sun-java6-jdk version 6.26-2natty1)

Some info about the graphics driver:

$ jockey-text -l
xorg:fglrx - ATI/AMD proprietary FGLRX graphics driver (Proprietary, Disabled, Not in use)

And:

$ sudo lshw -c video

  1. I asked on Twitter, and one of IntelliJ IDEA developers (Denis Zhdanov) replied:

    I've encountered it under my ubuntu as well. Looks like a native problem because it persisted even after killing all java processes

    I switched to java7 and Xrender pipeline eventually and don't observe the problem so far

    I'm now trying if this helps, and will report back later. To recap, this is what I did:

    1. Switched to running IDEA on JRE 7. (If unsure of Java version used, check the Help -> About dialog.)
    2. Set the property -Dsun.java2d.xrender=true. As Denis points out, the best way is to edit the file <idea_home>/bin/idea.properties and add sun.java2d.xrender=true on a new line.

  2. Run xkill from the "Run command" window, which can be invoked using alt+f2. Next, click the popup and its process should be killed.

    Now, of course, this appears to be a bug in the application. I recommend you report it to the developers.
