Description Conrad Groth CLA 2018-03-04 06:58:49 EST
Follow up for issue found during work on bug 480586:
...the fading is disabled if any background color is set, even if it's the system default...

Niraj Modi suggested this solution:
Searched for the possible reason for this implementation.
Below bug seems related and which may have introduced a fix to the bad drawing with expand(plus/minus) in Tree class (possibly for WinXP only):
https://bugs.eclipse.org/bugs/show_bug.cgi?id=155817

Going by the code comments also, Tree's plus/minus is more of WinXP specific UI element. And if this assumption is correct and since WinXP is no longer relevant:
We can try to introduce this fading animation effect back for Win7 and onward OS version.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
