#2239 new defect

Inactive memory mapped video windows playback loosing a lot of frames

Description

When I attach windows locally and they are memory mapped, windows' priority is real time only when they are active. For example, when I run firefox on youtube or a video player, if the window is active, the video plays fine, but when it's inactive, the video plays like a slide show.
Remotely attached xpra windows (displayed with codecs, such as h264), don't have such problem. Inactive windows don't slow down, as they when they are memory mapped. Remotely attached codec windows play normal, even if they are inactive. Also, local windows ran without xpra behave normally, i.e. don't slow down, if inactive.

Please provide more details as per wiki/ReportingBugs, in particular your DE, xpra info captured when the problem occurs, etc

Does this also occur when you set --mmap=no?
