05:28 <lina> I think there is a GEM object leak somewhere still, but it's not clear what causes it. I noticed shmem usage increasing, and killing kwin resets it. But it's not exported dmabufs. And I think I've only seen it happen with the lid closed?

05:28 <lina> It could be a kwin bug for all I know...

05:33 <lina> The smallest possible 60Hz leak is about 1MB/s (a single 16K page), which is a lot more than what I'm seeing. But maybe it has something to do with the screen locker clock.

05:34 <lina> On this machine, a single fullscreen framebuffer leak per minute (when the locker clock ticks) is still too much...

05:34 <lina> But if there's something else triggering a leak of around that size every 3-4 minutes that would start to add up

05:37 <lina> I'm going to log systemwide shmem usage under different conditions for a few hours at a time and see if I can at least figure out what causes it
