System settings window does not display on screen after moving the dockbar to Bottom

[Sivakumar Ganesamurthy]

Hi,

I opened the settings window fromt the top left corner.

I changed the dockbar position from left to bottom. After changing the dockbar to the bottom, the setttings panel does not show up on the screen.

While it shows up on the dockbar, Clicking on it shows the settings window that is open. But, the settings window does not show on the screen.

Let me know how this can be fixed.

The same problem happens for the software updater as well. After moving the dockbar to the bottom the software updater window does not show up. But, it is shown in the dockbar

I am unable to use the settings window to change the dockbar back to the "Left". This is really frustrating. Is there a workaround.....

Thank you for your bug report. Does it happen every time? The description is not really clear to me, is the problem that after setting the dock to be placed at the bottom of your screen all your open windows become invisible?
Do you use one or multiple monitors?
Could you add your journalctl from around the time of the issue?
