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?
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.
Not heard back, closing.
