[Bug]: Conky CPU graph misaligned at bottom edge in Wayland

What happened?

Under Wayland, Conky’s CPU graph body shifts/ overlaps with the box bottom border edge, but this issue doesn’t occur with XWayland using the same config, The graph body needs to move up by 1px maybe. Please refer image below.
