Latest mesa available through apt repos in stretch I just installed LMDE3 and not adding any ppa or messing with sources.d apt folders. The desktop works flawlessly with effects or without them. So there is no pretension to how it works but it prevents to run my game from full speed.

LMDE3 disable full screen compositing not work for steam "Brain Out" game which is java jar file and I have no such issue on Ubuntu 18.04.1 LTS on any DE but Cinnamon (used all of ubuntu redactions past month).

Install steam via apt repositories, install Brain Out game, run like cd .steam/steam/steamapps/common/Brainout/ ; java -jar brainout-desktop.jar get laggish stuttering when moving character through the screen

Normal behaviour game runs by openjdk-8 work almost without lags

  Also trying to enable DRI3 and disable swapbufferswait but its not related to compositing problem since it not disabled for particular java jar application. No matter what I enable/disable full screen VSYNC in Brain Out game title. Have no other quirks in grub, the config is just plain defaults.

cat /etc/X11/xorg.conf
Section "Device"
Identifier "r5 230"
Driver "radeon"
Option "swapbufferswait" "0"
Option "ColorTiling" "on"
Option "DRI3" "1"
Option "AccelMethod" "glamor"
Endsection

"Just curious if there some way to disable compositing at all like it done in Mate Mint/Ubuntu/Budgie editions by using some graphical settings up tool like exists in mentioned various distributions redactions, or maybe some console command could be passed to java app or Cinnamon compositor what ever its called (I just know in Mate it is called Marco)"

I only tested these on one steam game which I play "Brain Out". Will try to test on the other Linux native games. But mentioned game is on java. Sadly I didn't find any JVM options for display and changing vsync on/off in game does not get any effect. Not tested windowed mode but I think it will surely be composited too.

Native Linux games like Sauerbraten works normally.

bump. Its seems it only Steam games related bug I have measure FPS of "Gangs of space" game by in game FPS counter and it shows 50 to 10 drop downs.

How can it be work around, I am not willing to follow openbox + compton as people advice to me for playing few steam games ;( or maybe I go for these simple design.

It could be also that steam overlay or steam main window is showing up on all 4 work spaces.

I even didn't find out how to manage to kill 3 out 4 to leave only 1 one of them. There is no such settings in whole Cinnamon control panel.

And the bottom panel of LMDE3 is seems to be could oddly missing some applets which is locked and can't be deleted in Cinnamon control panel like work spaces switcher but it not showed up by default.

Well it could be probably closed. The solution is to install haveged daemon and to move away to clean gnome-shell without any gnome-shell-extension(s)-xxxxxxx, or if someone not like gnome-shell it could be switching to xfce4 + xfwm. Or aforementioned openbox + compton (the long way since openbox have its own bugs with steam).

Something was broken in Muffin or elsewhere I don't know but clean gnome-shell giving performance in games that runs through steam platform almost equal performance as Unity 7 session in Ubuntu 14.04.x LTS or even more.

And I now deal with the applets but well the comic situation is that I forced to use plain gnome-shell instead of Cinnamon as supposed to be...
