Eclipse Mars hover over methods is black after update

Question

I updated to Eclipse Mars. Now if I hover over methods I have black text on black background. Before updating from Luna I had yellow background, black text. How can I configure this hover over for methods? I am on Ubuntu 14.04.2 LTS.

Answer 1

The best workaround I have is this:

export SWT_GTK3=0

before starting eclipse. (You can also do: SWT_GTK3=0 ./eclipse)

Alternatively, you can now also do:

./eclipse --launcher.GTK_version 2

I found all GTK3 modes to be barely usable, and in a mess.

The "dark" (emo) mode still works somewhat, because there seem to be some hardcoded colors somewhere (ouch). I wish they would test better. This is just unusable. And I wish the GNOME people would stop breaking their stuff all the time, too. I hate everything they have been doing the last few years... they are totally designing their UI for a different audience than developers.

When trying out different themes/engines always restart eclipse completely (not using the "restart" menu) to make sure to pick up new environment variables etc.

You can set this as default, by adding export SWT_GTK3=0 into your $HOME/.profile which will usually be read on login (i.e. this will only be effective if you logout and login again).

Answer 2

I had similar problem. so i decided to install eclipse mars using oomph installer . guess what !! finally i have my eclipse without any GTK 3 problems.

Give it a try there is much more what oomph offers.
