Since few days (maybe since mid-Nov 2015) my KDE display shows strange behaviours. With some menus, the items don't show, I can only read them if I hover the mouse over them. The characters are very ugly and bold. But this occurs only with menus like the system menu or some menus like those in Konsole/Kate. With other applications like Firefox or NetBeans there seems to be no problem.

I'm currently running on Kubuntu 12.04.5 LTS.

The kernel is 3.2.0-61 generic on a x86-64 (Quad core I7).

KDE version is 4.8.5

My video setup is a GeForce GTS 450 with NVidia driver 304.131.

Notice that I apply the updates as soon as they are available.

I would like to know what happens because it is very anoying. I tried to erase the .kde folder but nothing changed... I don't suspect my video board because the problem occurs only with some menus. I rather suspect KDE...??????

Do you have an idea to solve my problem?

This could also be the outcome of a Java OpenJDK7-bug. Possible reference: Question 697515 Graphical Issues with Kubuntu

  • After reading the link you suggest, I found it looks very like my problem. I will try the solutions tonight when I will have my computer. Note that I could not guess that it could be linked to Java... ;-)

  • I did what you suggested. It seems to solve my problem but I want to test it for more than two hours before being more affirmative.

  • Testing a little longer is always o.k. & preferred. Nov 20, 2015 at 21:03
  • Thanks ellisistfroh, you gave me the solution! After more than three hours, no more display problem occurred. I believe the JDK was the problem.
