I am experiencing a strange issue with Ubuntu 18.04 that I don't know could have been caused by a wrong configuration or a conflict from recent application installs. What happened was whenever the child process of a GUI application exists, the parent GUI minimizes. Example cases would be:

Example 1:

Open Naulius, find a tar file and open it by double clicking. Select /tmp then click Extract. Immediately, the File Roller app that just extracted the files minimizes.

Example 2:

Open Nautilus, right click on a folder, click Open in New Window. Once the new window opens, close it. Immediately, the parent window also minimizes

Example 3:

Open Terminal, type file-roller. Once the File Roller opens, close it. The Terminal window also minimizes. This also happens with gnome-calculator. But this issue does NOT happen with firefox or gedit.

When working with multiple applications, I wish to group the visibility of 2 or more app/windows together, so they either minimize all or visible all, not necessarily maximized. Eg, say I want to have VsCode and Firefox visibility grouped so when I minimize VsCode, Firefox is also minimized and I can browse the web with Chrome full screen. Later when I restore VsCode then Firefox is also restored automatically.

I am aware of an extension called ShellTile that has grouping capability, but it appears to tile 2 applications fullscreen side by side which is not what I want.

I have my Logitech G502 mouse with many extra buttons so I wish to be able to hold down a mouse button, use scroll wheel to go through opened windows, release mouse button to select it.

The close keyboard shortcuts I found is Alt+Esc which maps Switch windows directly. To use it, I would hold down Alt button, press Esc repeatedly until desired window is shown, release Alt. An orange frame indicates the selected window.

I have experimented with xte and button sequences but found that they are very unreliable, especially some requires delays to register correctly.

In the end, I found this post and wmctrl which I mapped the single mouse key to this script and it cycled through the windows nicely. However, the way it worked it actually focused on the window thus piling up all the windows on my desktop. I wish to be able to find and select the window first before focusing on it, similar to Alt+Esc.

How can I do that?

I have VSCode installed and never experienced this issue before, but now after I installed some web camera utilities and video conversion I seemed unable to launch VSCode from Nautilus.

What works:
Open a terminal directly and type code

What doesn't work:
Open Nautilus, right click any folder, open with Other application > VSCode.
Open Nautilus, right click any folder, open terminal here, type code

Error message:

What is the root cause of this issue and how do I fix it ?
