`--experimental-backends` flag was removed in the recent released picom
v10. Using it now will result in the program exiting.
v10 also introduces its counter-part, `--legacy-backends`. However this
will be removed soon. Instead of adding this as an separate option, add
`extraArgs` option so for those that they want they can pass it manuall.
It is also more future proof.
Removed by upstream since commit:
bcbc410c92
This commit is included since v9 release:
https://github.com/yshui/picom/releases/tag/v9https://github.com/yshui/picom/releases/tag/v9-rc1 (the actual changelog)
While this doesn't break the config per see, it results in the
following warning in the logs:
[ DD/MM/YYYY HH:MM:SS.mmm parse_config_libconfig WARN ] The
refresh-rate option has been deprecated. Please remove it from
your configuration file. If you encounter any problems without
this feature, please feel free to open a bug report
Beside the above change we also remove an old workaround and also
write the configuration file to a well-known location in the user's
home directory.
