With the `wsfb' DDX, Firefox wired totals are stable (~9MB).
I can't reproduce this on my laptop (I don't have physical access to my workstation in the next 2 weeks). wired memory increase by about 40Mb when glxgears is running but goes back to the original value when glxgears exits. My laptop has this CPU: cpu0: "Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz" cpu0: Intel 7th or 8th gen Core (Kaby Lake, Coffee Lake) or Xeon E (Coffee Lake) (686-class), 2712.00 MHz cpu0: CPU base freq 2700000000 Hz cpu0: CPU max freq 3100000000 Hz cpu0: TSC freq CPUID 2712000000 Hz cpu0: family 0x6 model 0x8e stepping 0x9 (id 0x806e9) This is the same generation as my workstation, but not exactly the same graphics.
