Version: (using KDE 4.2.4) Installed from: Gentoo Packages When plugging a LUKS-encrypted volume into your computer, this is shown as "Volume (crypto_LUKS)" in the places panel. If you open now this device by clicking on the symbol and entering your password, then hover it's icon with the mouse, the text "Volume (crypto_LUKS)" moves ~5px up, which makes this look a little strange (See also screenshot in attachment). This is probably related to the code, moving the text some pixels up when having a volume mounted, to show the "Disk Free" bar below the text. For a crypt volume, there's no such bar available and may cause this issue.

Works for me in KDE Frameworks 5.47.
