SUMMARY

While using krfb under wayland with scaled display, krfb also tries to scale mouse coordinates, resulting in incorrect mouse movements.

STEPS TO REPRODUCE
1. Set desktop scale to 200%
2. Run krfb
3. Move the mouse and compare cursor locations between the host and the client

OBSERVED RESULT
Cursor moves twice more pixels

EXPECTED RESULT
Cursor should move exactly the same as shown on the client
