Describe the Bug

I am running sunshine on a headless VPS server using software encoding. When using X11 for desktop capture it works fine, however the other day I switched to using KMS which also works, however my machines memory usage creeps up over the course of a day. Using htop I see that when I first start sunshine I am using around 1gb total of memory, and by the end of the day the entire 8gb is full and my server is almost unresponsive. Interestingly htop reports that the sunshine process is still only using 3% of my systems memory which makes me wonder if there is actually a bug in the modesetting/kms drivers rather than sunshine. I can restart the sunshine process and memory usage drops back to around 1gb. I am sorry that I cannot offer any more details right now, hopefully I can receive some help on how to provide some more useful feedback regarding this issue.

Expected Behavior

Expecting that memory usage should remain constant
