UPDATE: Attempt drag windows to left/right screen edge reproduces the bug as well. It seems like the freeze occurs whenever the animation of future window size filling the space tries to play (it plays eventually, after the freeze). Note that maximizing animation itself works flawlessly, and I can maximize windows via "maximize" button or by double-clicking their headers without delays. UPDATE #2:
The problem doesn't occur in Wayland sessions.
So, after a lot of experimentation with video drivers and Xorg configuration I was able to fix this issue. That involved switching back and forth between Nvidia and Nouveau drivers via the Driver Manager (Ubuntu's version).
I'm still not sure how exactly it was fixed, but the one notable difference is that modesetting driver is not loaded as seen in "inxi" output:

SUMMARY I'm running KDE Neon User Edition. After recent upgrade to Plasma 5.15.4 now every time I drag a window to the top edge of the screen to maximize it, the desktop *always* becomes unresponsive for exactly 13 seconds (I measured several times using my smartphone's clock). After that, the window usually maximizes normally. Now, for me, this bug persisted since I started using KDE Neon (which was around Plasma 5.12.*, I believe), *HOWEVER* until the recent upgrade (to 5.15.4) it the bug was occurring just occasionally. It worked without freezes most of the time, so I could live with that. Now the bug always persists, which kind of make system unusable for me (I'm looking into downgrade to 5.15.3 at least). STEPS TO REPRODUCE 1. Attempt to maximize any window by dragging it to the top edge of the screen (the option "Maximize windows by dragging them to the top edge of the screen" should be enabled in System Settings > Desktop behavior > Screen Edges) OBSERVED RESULT Desktop always becomes unresponsive for 13 seconds, after which window is maximized properly. EXPECTED RESULT Window maximized by dragging immediately. SOFTWARE/OS VERSIONS KDE Plasma Version: 5.15.4 KDE Frameworks Version: 5.56.0 Qt Version: 5.12.0 Kernel Version: 4.18.0-17-generic ADDITIONAL INFORMATION I have multi-monitor setup, but bug is reproducible even with one monitor disabled. Disabling Compositor has no effect.
