Attempt to run Pycharm on Cosmic DE Beta1 as second DE for Arch Linux KDE Plasma 6.4.5

 Setup Cosmic as second DE for KDE Plasma , reboot select COSMIC from drop-down SDDM menu 

$ sudo pacman -S cosmic-session cosmic

$ sudo reboot

It appears that the only way to create new python code file (or any other file ) for particular project requires one or another way of manual intervention.  In particular it may be done via dolphin file manager either via `touch -f NewPytonFile.py` in correspondent directory  




















Run 3D plotting python script in floating windows style










Now switch to tiling windows style for current workspace










Switching between floating style windows to tiling style windows mode and vice versa works fine on Cosmic DE. 

By the way, I have to notice that performance of CachyOS instance ( bare metal ) vs native Arch Linux instance on the same box been assembled with Intel Xeon CPU E5-2690 ( Haswell ), 32 GB RAM and WD NVMe SSD is really impressive, moreover some issues which show up in Cosmic Beta as dual DE appear to be gone when basic instance is running CachyOS.
