I think I'm seeing this as well with a custom theme:

This is using version 8.0 (64-bit) on Linux.

I think this was introduced in 7.1-beta.40+4dbe0f784.

7.1-beta.39+0acfcd3f9:

7.1-beta.40+4dbe0f784 is also the version that hampered the lighter themes (hence the color difference in the above screenshots):

Also, like in the other issue I linked above, once I zoom in far enough the ghosting disappears (and the theme is rendered correctly):

At some zoom level:

Zoomed in one more step:
