Bug#884829: Still present in Debian 11

[Martin Pavelek <he29@mail.muni.cz>]

Hi,

I can confirm this bug still exists in xserver-xorg-core 2:1.20.11-1+deb11u1; I have been suffering from it 
ever since I upgraded from Debian 10 to Debian 11 a few months ago. The memory usage of Xorg process keeps 
growing until eventually the laptop becomes unresponsive and OOM killer starts reaping random processes and 
everything comes crashing down.

In my case, I tracked the problem mainly to xfdesktop4 and xfce4-panel (leaking about 5 MB per hour when the 
machine is idle). Only when I kill both of them the increase in memory consumption stops, although the already 
consumed memory is not released. Using the machine makes the rate of leaking worse, so clearly there are many 
other sources that can trigger the leak.

I can also confirm that if I install audacious and play it with the visualization on, the leak increases to 
about 57 MB per hour, so the problem I experience is very likely the same one as reported here. I'm really 
happy to finally learn I'm not crazy and someone else noticed the issue as well (although I did not expect it 
to go all the way back to 2017).

Is there anything I can do to help move this along? Should I try testing the patch? Or open a bug report upstream?

Thanks,
Martin
