Package: libvncserver1
Version: 0.9.13+dfsg-2
Severity: normal
Dear Maintainer,
* What led up to the situation?
I run x11vnc over a gigabit direct connection with:
x11vnc -usepw -ncache_cr -display :0 -loop -noxdamage -shared -nomodtweak -noshm
Upgrading to 0.9.13+dfsg-2+deb11u1 and then reconnecting my client caused
x11vnc
to run very slowly. `*** fb_push ublen NOT ZERO: 3290940` appeared in the log
very frequently. From my logs, I had only seen this message once before, 10
months ago.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Ineffective: reconnecting, restarting x11vnc, or rebooting
Effective: downgrading to 0.9.13+dfsg-2 and reconnecting
* What was the outcome of this action?
reconnecting, restarting x11vnc, or rebooting: x11vnc remained sluggish and
`fb_push ublen NOT ZERO` continued to appear
downgrading to 0.9.13+dfsg-2 and reconnecting: went back to a usable speed
* What outcome did you expect instead?
I did not expect a minor update to change the speed of x11vnc.
