I have the AMD/ATI Bonaire Radeon R7 200 GPU on my rig. This works well with Marco, but has persistently been a bit buggy with Compiz. I am pretty sure the Compiz issues I have experienced are related to my card and not due to Compiz itself, due to reading of others’ similar issues with Compiz and this card. However, given that Marco does not use the GPU for compositing, it is slightly less effective at eliminating screen tearing than Compiz. Consequently, I searched for a simple GPU hardware compositor that worked well with my AMD card and it turned out to be Compton. Basically it involves leaving Marco enabled as the windows manger with compositing turned off and having Compton running alongside to handle the hardware compositing instead.
Though there are many subtle switches available for Compton, I run it with the following command:
compton -c -m 0.8
This gives full hardware compositing with panel and menu shadowing and menu transparency. The menu transparency can be turned up or down by altering the value from 0 to 1. But, I find 0.8 is a nice level.
All of the above being the case, I was wondering if it could be parcelled up into Mate Tweak as an optional feature to use in conjunction with Marco for those users using AMD cards.
