VSync/tearing performance issues
I thought I would give
metacity a try given your recent Vulkan work. Stepping up from
marco I'm seeing horizontal tearing, laggy rendering and overall poor performance when moving windows. Reminds me pre-XPresent era a little bit. Disabling Vulkan makes no difference. Compositing seems to be enabled:
$ gsettings get org.gnome.metacity 'compositing-manager' true
My screen is tiled 5120x2880 with properly detected and assembled XRandr logical monitor:
$ xrandr --listmonitors Monitors: 1 0: +Auto-Monitor-1 5120/600x2880/340+0+0 DP2 DP1
Any advice for further debugging?
