client side memory leak

[karlkleinpaste]

i had noticed that my client system's main xpra process was growing severely over the course of a day. so i started a shell one-liner to sample it every half hour. it grows to many Gbytes and, left unattended, will succumb to the OOM killer. observe %MEM+VSZ+RSS.

installed with python3 ./setup.py install as of git pull early this morning, but i've noticed it happening for a while. about a dozen windows were open, and not opening new ones during this time, nor closing any. (bunch of terminals, couple xemacs, zenity, nvidia-settings, ...)

Please provide more details as per https://github.com/Xpra-org/xpra/wiki/Reporting-Bugs

Everything is relevant until proven otherwise. ie: #2730 (comment), #1662, #535 (comment) (a codec), etc.

Could also be something like mcfletch/pyopengl#47
So it's worth trying to disable every feature to see if any of them stop the leak.

i've just realized that i haven't seen this happen in a while. i use "git pull" + rebuild semi-regularly, so perhaps whatever problem has been solved elsehow. if you wish to close this, feel free.
