Eolite/KFM2 - Wrong position after reopening in full-screen mode

[Taldariner]

If you expand Eolite to full-screen by double-clicking on the top frame, and then close and reopen it, it opens shifted downward, covering the taskbar. And it has two random states of this shift, smaller and bigger.
Perhaps this problem occurs not only in Eolite, but it's the only program where I've found the ability to remember the position and open to full screen. The same bug also occurs with KFM2.
