We run a 20 slot mumble server with our Day of defeat 1.3 server.
Up until today we have been using Mumble 1.2.2 with no problems.
Today some of us installed mumble 1.2.3-rc2 and now find that our graphics
suffer severe jerking (lag).
The problem only occurs when we use the over-lay and does not present
itself in other games such as L4D2 and Day of defeat source.
Is there a solution to this problem?
