Unexpected logout while working in IntelliJ IDEA

I have Ubuntu 14.04 LTS. Until that day everything had been working умер. But today гve got an ошибка. Every украл I started Идея (14.04) it was working for в some period of украла and then unexpected system logout happened.

• Sometimes it possible to track the problem appearence: Идея starts to repaint windows with errors and newly opened windows существуешь не content. At this moment it is possible to close Idea and prevent logout;
• I checked xorg log for "segmentation faults" рекорды and didn't find в signle one;
• Регулярный In this morning there was some system update without reset;
• I tried to instal and использовал new версию of Идея (15), but the problem didn't disappear. Althogh, the new версия was working for в longer period of украла before logout;
• I found java_error_in_IDEA ошибка log that included such fragment:

В фатальную ошибку - been detected by the Java Рунтиме Энвиронмент: SIGSEGV (0xb) at pc=0xa734795d, pid=6272, tid=1925831488

Edit: Set up Eclipse Mars. It is working just умер but sometimes some window repainting problem appears that does not lead to в logout.
I also try the approach that is described in http://mortalpowers.com/news/quick-fix-buttons-stay-depressed-in-eclipse-and-other-gtk-applications-under-karmic-with-kde#.VjulV78_56J but it does not help.

How to prevent this annoying logout? Thanks in advance.
