#xrender backend with opengl solves "laggy drag" issue on 14.04
#glx backend with opengl-swc works with <=13.10
# These are important. The first one enables the opengl backend. The last one is the vsync method. Depending on the driver you might need to use a different method.
# The other options are smaller performance tweaks that work well in most cases.
# You can find the rest of the options here: https://github.com/chjj/compton/wiki/perf-guide, and here: https://github.com/chjj/compton/wiki/vsync-guide

# The shadow exclude options are helpful if you have shadows enabled. Due to the way compton draws its shadows, certain applications will have visual glitches
# (most applications are fine, only apps that do weird things with xshapes or argb are affected).
# This list includes all the affected apps I found in my testing. The "! name~=''" part excludes shadows on any "Unknown" windows, this prevents a visual glitch with the XFWM alt tab switcher.
