Xpra: Ticket #1412: High CPU load with Xpra 1.0 on Win 10

I observe high CPU load (100% on one core) when using Xpra 1.0 r14502 on Win 10 doing nothing (no window is being displayed). I just attach to a remote xpra server on Ubuntu.

The high load occurs as soon as it is attached - no matter if windows are displayed or not and it is a specific thread.

In the screenshot attached, the process information can be seen using Process Explorer.

A probably useful remark: The issue seems to be the speaker. If I start with speaker=off it works normally.

Please see wiki/ReportingBugs and specify: server version and log file, client command output, etc.. In particular the codec that is being used, can you try a different codec? ie: speaker-codec=mp3

windows 10 desktop with opus+ogg sound forwarding, using 4% CPU

As you can see here: windows 10 desktop with opus+ogg sound forwarding, using 4% CPU

A default installation on Windows 10, connected to a Fedora 25 server (running 2.0 beta or 1.0 - no difference), uses opus+ogg for speaker forwarding and uses up about 4% of CPU.

No problem here so lowering priority.
