Questions[window-placement](ubuntu)

After updating to Ubuntu 20.04 I'm not able anymore to set 2 windows side by side (left and right) and change their percent of the screen while moving the join (in the middle)

This was possible in previous version like Ubuntu 19.10. Maybe they changed the way of doing it. Let me explain myself with graphics: Move windows stuck together in Ubuntu 19.10

Steps to reproduce it:

1. Update to Ubuntu 20.04
2. Pair side-by-side windows, ex: FireFox (left) and Visual Studio Code (right) or OBS (left) and Chromium (right)...
3. Now that the 2 windows occupy 50% of the available area try to move the middle.

Note: If one of the windows is the internal Ubuntu File Browser you can do it but when you are using external apps (no those ones from the system) you cannot.

In 19.10, Kubuntu, Lubuntu, Ubuntu Mate and Xubuntu all have the ability to make a window occupy the upper half or the lower half of the screen using Meta+Up and Meta+Down respectively. But Ubuntu 19.10, out of the box, doesn't: instead, Meta+Up and Meta+Down maximize and restore windows.

Why is that?

I installed PyCharm Community Edition via Ubuntu Software Center, and when I try to open the application it indicates that PyCharm is open and I can see the window when I hover over the icon, but it won't display on the desktop in full view. I have already tried to uninstall and reinstall this, and the issue continues to persist.
