How to restore layout in Libreoffice Math

My work environment is openSUSE Tumbleweed with Plasma5. Because of manual mistake, I moved the border of “elements” component and found that it could not return back to its original place. To solve this problem, I tried the same thing to the command component and could not restore it too. How can I restore its original layout? Or is it a bug in kde5?Thanks.

This is the way for Windows, but it might work for openSUSE too. Take the command-Window with the mouse on the title bar and drag it down to the bottom edge of the application window. When the lower edge of the title bar reaches the bottom edge of the application window, you will get a hatched frame border. Move a little bit slowly up and down, if it doesn’t appear. When the hatched frame border is shown, release the mouse.

You can tread the element-window the same, only it needs to be dragged to the left edge and the hatched frame border appears, when the mouse is near the application window edge.

Another way is to use Ctrl+Shift+F10. That docks the window to its default position and make it flying next time. That shortcut is a toggle. The window needs to have the focus. If it does not work using the keyboard, then it is a bug. Keyboard handling should always work for accessibility.

Unfortunately, it can not work for openSUSE. In KDE5, the compenent dragged became a standlone window.

The current setup is stored within your Profile. Therefore, try resetting your Profile (Q59016) (fully reversible).
