====== Eclipse Luna speed up and fix flickering ======

I used to work with Indigo and it was pretty good, but once in a while it's important to upgrade to have some new features so I was forced to install Luna.

**First huge problem**\\
Try to move the editor tabs: everything disappear. The entire Window turn to gray (on Windows some experience it as black)

**Second problem**\\
A lot of flickering everywhere, even on other windows not Eclipse related (e.g file manager, pluma, etc.).

**Third problem**\\
Slow, slow slow. My i7 workstation can't scroll the editor properly. What do they expecty me to use? A Cray-X Mainframe?8-O When I use the down arrow, it's so slow that the keys are queued and I can't figure out when depressing the key to stop where I want to.

**Solution**
Make a bash script like this one:

<code>
#!/bin/bash
export SWT_GTK3=0
export UBUNTU_MENUPROXY=0
cd /opt/eclipse
./eclipse -showlocation
</code>

edit the launch icon of Eclipse to use that script instead of eclipse directly.
Try it. No more flickering and good speed is back!

**FIX the theme**\\
With the above modifications the gtk menu will look a bit messy. To fix it, go in
**window->preferenced->general->appearance** and set **classic theme**
and that's it!
