--- Comment #18 from Michael Marley <mich...@michaelmarley.com> --- I just made a startling discovery. The kwin packaging for Debian/Ubuntu (which I had been using all along) doesn't set CAP_SYS_NICE on kwin_wayland, so the attempt to set a higher priority for the input and output threads was of course failing. Setting CAP_SYS_NICE manually alone makes a minor difference, but when combined with increasing the safetyMargin to 3000us, it almost entirely stops the frame dropping. I know one of the maintainers, so I'm going to ask him why CAP_SYS_NICE isn't set. -- You are receiving this mail because: You are watching all bug changes.
