meld screenshot

Description of problem:
File comparision in meld is unreadable under KDE (see attached screenshot).

Version-Release number of selected component (if applicable):
$ rpm -qv meld
meld-3.12.1-1.fc21.noarch

kde: 4.14.3 (fully updated to updates-testing as of now).

How reproducible:
100%


Steps to Reproduce (just to be sure we're using defaults):
1. Create a new user 'kdetest'
2. Login as 'kdetest' using 'KDE Plasma Workspace'
3. launch 'meld' /etc/services /etc/services

Actual results:
Text to compare is unreadable.

Expected results:
Text should be readable.

Additional info:
On F20 there wasn't such an issue.
Comment 1 Rex Dieter 2014-12-29 18:13:07 UTC 
Triaging to kde-workspace for now, though this is more likely a change in meld (kde differences between f20 and f21 are very minor)
Comment 2 Damian Wrobel 2014-12-29 18:19:14 UTC 
Seems to similar to bug #1118898.
Comment 3 Rex Dieter 2014-12-29 18:31:58 UTC 
I would argue this is a meld bug, it seems to unconditionally use a black background for unchanged text, regardless of active color scheme (which obviously can lead to problems if text contrast vs. this hard-coded black is too low)

Re-assigning...

I followed [1] and have cloned the latest meld sources and the issue seems to be fixed (git: 936b6ab).

Comment 5 Pavel Alexeev 2015-01-12 15:40:53 UTC 
I also could reproduce it and it is very annoying (unchanged text is not visible at all).

Possibly it is introduced by:
https://mail.gnome.org/archives/commits-list/2014-October/msg01998.html
https://mail.gnome.org/archives/commits-list/2014-October/msg05560.html

I also tried and commenting lines:
        fixes_provider.load_from_data(
            "MeldSourceView { background-color: rgba(0.0, 0.0, 0.0, 0.0); } "
            "MeldSourceView:selected { background-color: %s; } " % color)
in /usr/bin/meld solve problem for me.

I've attach screenshot how it looks by default.

Please try to use the 3.13 [2] version from koji.

Comment 7 Bruce-Robert Pocock 2015-01-19 21:40:16 UTC 
+1 on fix:

Same thing occurring in stock Gnome-3 desktop as well. (Upgraded system from ƒ20, not clean install, however.) Identical presentation (solid black outside of diff regions; text visible when highlighted). Koji build meld.noarch 0:3.13.0-1.fc22 → works fine.

This is fixed in upstream meld 3.12.3.  Any chance of pushing out an update?
