I have compiled a video of the issue here: https://youtu.be/6ENuld1ee_Y

Issue in short: KDE/Plasma freezes (for a couple of seconds) when a window is dragged to tile or dragged to the top to maximize when using nVidia GPU. This does not happen when using Intel's Integrated GPU.

Please Note: ALL details have been mentioned clearly in the video description.
If more information is required, I am willing to share further.
