Package: x11vnc
Version: 0.9.16-8+b1
I am using VNC via SSH using x11vnc to access my remote desktop from home. x11vnc is called with the following arguments: 


x11vnc -quiet -safer -localhost -nopw -once -display :0
Since upgrading to Debian Bookworm about half a year ago, update performance degraded rapidly and the following messages started showing up in the output from x11vnc on various events (opening of windows, focus changes): 


PORT=5900

The VNC desktop is:      localhost:0

*** fb_push ublen NOT ZERO: -1616838418
*** fb_push ublen NOT ZERO: 932745215
*** fb_push ublen NOT ZERO: -1644826
*** fb_push ublen NOT ZERO: -1711237889
*** fb_push ublen NOT ZERO: -1711237889
The same issue has been reported by at least one other user as well in the Debian forums [1].
After erroneously assuming this to be caused by a patch that was backported to Bullseye (see [2] and [3]), it appears now to be a packaging bug as recompiling x11vnc locally fixes the issue.
