SUMMARY
The wlfreerdp window has wrong size if global global scaling is used.
It does not matter whether wlfreerdp is started from kdrc or directly from the terminal.
The window size is too large by exactly the global scaling factor.
E.g. scaling factor 125 %:
On a 1366 x 768 pixel screen, wlfreerdp must be started as follows: wlfreerdp /v:<server> /size:1100x550 to obtain a window of approximately 1366 x 768 pixels.

STEPS TO REPRODUCE
1. Start RDP Session from KRDC with e.g. actual size
or 2. Start RDP Session from KRDC with any size
or 3.  Start wlfreerdp directly from command line with any size

OBSERVED RESULT
1. wlfreerdp window is too big (the window is as much larger as the scaling factor)
2. same from terminal

EXPECTED RESULT
kdrc or wlfreerdp take the global scaling of the Plasma Desktop into account when entering the window size.

ADDITIONAL INFORMATION
Comment 1 Fabio 2024-11-23 16:25:13 UTC 
Krdc doesn't use xfreerdp/wlfreerdp anymore since version 24.02. It now directly links to libfreerdp, and fixes has been added to correctly support scaling even on wayland.
