Description Blazer Silving 2025-11-30 17:06:06 UTC 
SUMMARY
I use two monitors in portrait-landscape mixed orientation. A top-level layout out of screens (as VNC presents) will normally have black unused space. 

krfb draws windows in this region, where x11vnc does not. 

STEPS TO REPRODUCE
1. Use mixed monitor orientation that would lead to the layout above (screenshot). 
1. Open a window and manually resize or move it beyond the screen edge. 
2. Connect using krfb, notice the window contents drawn beyond the screen edge. 

EXPECTED RESULT
Window contents beyond the screen edge shouldn't be drawn.
