xpra info, when the image is blurry: http://paste.akawolf.org/view/A6svZ

As per the log file, this seems to be a shadow server.
I think that using --scaling=0 should fix this.

Maybe we should give a hint to the video encoders to reduce the chances that auto-scaling will kick in when using shadow servers.

Using "--scaling=0" fixed the problem.

comment:8 Changed 6 years ago by Antoine Martin

FYI: as of r10257, we try not to automatically downscale the picture in the shadow servers.
