Resizing window sometimes causes freerdp to hang, sometimes blocking all keyboard input

[LinAGKar]

Describe the bug
Sometimes, when the FreeRDP window is resized, it will completely hang, to the point where it even stops responding to SIGTERM, needing to be SIGKILL:ed. What's worse, sometimes when this happens all keyboard input within the X session will be blocked, requiring you to switch over to a VTT (ctrl+alt+f1) to kill it.

To Reproduce
Steps to reproduce the behavior:

1. Launch freerdp
2. Repeatedly maximize and restore the window until the bug happens

Expected behavior
It should not hang

can not reproduce, debian 12/gnome here (target windows 10 and 11)

Get the same thing on a different machine with OpenSUSE Tumbleweed, also with Plasma X11. Maybe it depends on Plasma vs GNOME, or X11 vs Wayland in case you're using Wayland.
