# "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.
#
# clip-shadow-above:::
# Controls wether shadows that would have been drawn above the window should
# be clipped. Useful for dock windows that should have no shadow painted on top.
#
# 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
Run picom
Run any windows game using Wine (I experienced this with several games. "Me, Myself, and Die" as a specific example)
Expected behavior
Little - no loss in performance or issues compared to when picom is not running.
Current Behavior
Severe performance issues resulting in a desktop-wide ~15 updates per second and audio crackling.
Other details
I installed and tested the compositor 'unagi' and found that it did not have this issue to any appreciable degree.

(default: 1.0) # # max-brightness = 1.0 # Make transparent windows clip other windows like non-transparent windows do, # instead of blending on top of them. # # transparent-clipping = false # Set the log level. Possible values are: # "trace", "debug", "info", "warn", "error" # in increasing level of importance. Case doesn't matter. # If using the "TRACE" log level, it's better to log into a file # using *--log-file*, since it can generate a huge stream of logs. # # log-level = "debug" log-level = "warn"; # Set the log file. # If *--log-file* is never specified, logs will be written to stderr. # Otherwise, logs will to written to the given file, though some of the early # logs might still be written to the stderr. # When setting this option from the config file, it is recommended to use an absolute path. # # log-file = "/path/to/your/log/file" # Show all X errors (for debugging) # show-all-xerrors = false # Write process ID to a file. # write-pid-path = "/path/to/your/log/file" # 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. # # clip-shadow-above::: # Controls wether shadows that would have been drawn above the window should # be clipped. Useful for dock windows that should have no shadow painted on top. # # 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`. # wintypes: { tooltip = { fade = true; shadow = true; opacity = 0.75; focus = true; full-shadow = false; }; dock = { shadow = false; clip-shadow-above = true; } dnd = { shadow = false; } #popup_menu = { opacity = 0.8; } #dropdown_menu = { opacity = 0.8; } }; ```Steps of reproduction
Expected behavior
Little - no loss in performance or issues compared to when picom is not running.
Current Behavior
Severe performance issues resulting in a desktop-wide ~15 updates per second and audio crackling.
Other details
I installed and tested the compositor 'unagi' and found that it did not have this issue to any appreciable degree.
