Eclipse:

Version: 3.8.1.v20130118-180812-9jF7oIBFG8eU2pim-VbIlTuQjY0RWWK3x-bv4I
Build id: M20130131-0800

Version: 4.2.1.v20130118-173121-9MF7GHYdG0B5kx4E_SkfZV-1mNjVATf67ZAb7
Build id: M20130204-1200 

SO:
  Ubuntu 13.04 Ringtail 64 bits

Java:
  java version "1.7.0_21"
  OpenJDK Runtime Environment (IcedTea 2.3.9) (7u21-2.3.9-1ubuntu1)
  OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)


When editing a file (text or java source file) the caret blink frequency is not constant and when moving the cursor to the left or right, the caret disappears. This strange behavior only occurs if "Smart Insert Mode" is enabled.

After disabling "Smart Insert Mode", the caret blink frequency goes back to normal, but when moving the cursor to the right or left, one is left with a dotted line above and below the line.

Screenshot attached.

Can you also attach a screenshot from the Text editor?
Comment 2 Dani Megert CLA 2013-05-06 05:57:50 EDT

Eclipse caret problem screencast
Comment 4 Leonardo Nicolás CLA 2013-05-06 15:19:16 EDT 
I recorded a screencast comparing gedit with Eclipse caret behavior.
Comment 5 Leonardo Nicolás CLA 2013-05-06 22:02:40 EDT 
I tested the Eclipse using Gnome Shell 3.8 instead of Unity and the problem didn't occurred.
The computer I'm using doesn't have a 3D video card.
Is it possible that the problem is associated to Unity without a 3D graphic card?

Is this bug still reproducible with Neon? Now that Eclipse defaults to GTK3 this might be fixed.
Comment 8 Leonardo Nicolás CLA 2016-05-18 16:06:39 EDT 
Alexander

I have tested the Eclipse Neon and this strange behaviour did not occur anymore.
Comment 9 Mickey Mouse CLA 2016-12-01 06:51:19 EST 
I still experience this bug [and others] with Fedora 24, GTK 3, oracle java 1.8.0_112, eclipse 4.6.1 CDT 9.1.0.201609121658 :/
