There should be a "Keep window thumbnails" option. Thumbnails should be shown in task manager previews.
Linux/KDE Plasma: Manjaro testing and stable/Plasma 5.23.4
(available in About System)
KDE Plasma Version: 5.23.4
KDE Frameworks Version: 5.88.0
Qt Version: 5.15.2
Under `System Settings > Display and Monitor > Compositor` I have these settings:
- Scale method: Smooth
- Rendering backend: OpenGL 3.1
- Latency: Balance of latency and smoothness
- Tearing prevention ("vsync"): Automatic
I'm using an integrated AMD Cezenne GPU and 5.15.x kernel. The "Keep window thumbnails" was available on this system on Wayland for a while and it worked well, but it seems to have disappeared after an update.

Settings panel with option present (different system with old Plasma)
Should also mention that I'm using PireWire 0.3.40 and WirePlumber 0.4.5.
Thumbnails are automatically kept on Wayland. However a bug sometimes prevents this from working. See Bug 446061.
