582 - Minor - Thumbnails view text background color

[Dreamer]

In thumb view, if FC is inactive, the text background color of actual file is white, also if FC is active, the text background color of ALL files is white.

It happens also if dragging the files to subfolders (moving).

Also when renaming the item, for a moment.

Fixed for the release 583.
