[Python-apps-team] Bug#711181: xpra: spinners consume a lot of CPU time unnecessarily

[Timo Juhani Lindfors]

Package: xpra
Version: 0.9.4+dfsg-1
Severity: wishlist

My laptop is usually connected to at least two xpra servers. If the
network connection is bad I frequently see xpra drawing spinners over
all windows. This is a good indicator but I think it uses bit too much
CPU time causing my laptop fan to accelerate when the 3G connection
drops:
