# Window type settings
# 
# 'WINDOW_TYPE' is one of the 15 window types defined in EWMH standard: 
#     "unknown", "desktop", "dock", "toolbar", "menu", "utility", 
#     "splash", "dialog", "normal", "dropdown_menu", "popup_menu", 
#     "tooltip", "notification", "combo", and "dnd".
# 
# Following per window-type options are available: ::
# 
#   fade, shadow:::
#     Controls window-type-specific shadow and fade settings.
# 
#   opacity:::
#     Controls default opacity of the window type.
# 
#   focus:::
#     Controls whether the window of this type is to be always considered focused. 
#     (By default, all window types except "normal" and "dialog" has this on.)
# 
#   full-shadow:::
#     Controls whether shadow is drawn under the parts of the window that you 
#     normally won't be able to see. Useful when the window has parts of it 
#     transparent, and you want shadows in those areas.
# 
#   redir-ignore:::
#     Controls whether this type of windows should cause screen to become 
#     redirected again after been unredirected. If you have unredir-if-possible
#     set, and doesn't want certain window to cause unnecessary screen redirection, 
#     you can set this to `true`.
#

Steps of reproduction

enable shadows
open a full screen window on the left monitor
see their shadows from the next monitor

Expected behavior

no shadows appearing in the next monitor

Current Behavior

shadows appearing in the next monitor

Stack trace

Steps of reproduction 2

have borders enabled in the window manager
slowly move a floating window

Expected behavior

it simply moves the windows, smoothly

Current Behavior

the border bugs out when moving

Other details

A video of the border bugging out.

I have tried toggling basically every setting in the .config, nothing worked. It happens only in this fork, on normal Picom it's completey normal (both, the shadow bug and this border one)
