Memory leak when running for several days
I have pavucontrol installed from the Arch repository; the version is listed on the package as 1:4.0-2. (I can't find the option to check the version number within the app.)
I noticed that my computer was low on available memory. I ran htop, and it told me that pavucontrol (which I've had running for at least a week or two straight) was using 25% of my RAM. I quit pavucontrol using killall
(since the close button didn't seem to work) and my RAM usage went from >90% to <70%.
This can easily be worked around by quitting the program when it's been running for a long time, but I just thought I'd bring it to your attention.
