Bug: Highlighting color in editor is different and unpredictable

[dpetratsch]

• VSCode Version: 1.20.1
• OS Version: Win10

Steps to Reproduce:

1. Search for text in files and cycle through the results
2. Found occurences are highlighted in an unpredictable manner althouh the text is 1:1 the same

When cycling between the results with F4 / Shift +F4 some elements get highlighted with different colors. In this case the first result is darker, all following colors are light as in the screen.

its definitely not a theme problem as this is the same in whatever theme is selected.

Currently, all results are highlighted in one color, in this case yellow, and the current selection has a different highlight color, in this case grey. Are you seeing different behavior than that/do you expect different behavior? Here's a reference of the theme colors: https://code.visualstudio.com/docs/getstarted/theme-color-reference

The two colors should be editor.findMatchBackground and editor.findMatchHighlightBackground

Yes, the strange thing is that the first occurence got the active focus and the following not when cycling through the results. I can't give you any further hints for reproducing the problem as the positions are changing in a random manner.

Here is another example:
Line 79 the active and matched highlight, but there are also 4 lines more having the active color, this is just strange and not reproducible in any way:
