--- Comment #20 from Paul <holle...@cs.dal.ca> --- Somewhat more concrete data: grep memfd:xshmfence /proc/$(pidof kwin_x11)/maps | wc If I alt-tab quickly, the count does not change. However if I keep alt held long enough for the thumbnails of open windows to appear, then the count increases by 2. In my current session the count has increased from 49 to 93. -- You are receiving this mail because: You are watching all bug changes.
