Bug#897659: fix

[Br1z0n <br1z0n@protonmail.com>]

Control: reassign -1 compton 0.1~beta2+20150922-1
Control: retitle -1 compton with mesa 18.0.2-2 - scrambled/tinted graphics on glx mode (with tmp. fix)
Control: severity -1 normal

I have found a fix for this issue on compton's github: https://github.com/chjj/compton/issues/477#issuecomment-370188534
Setting these config settings under ~/.config/compton.conf allows compton to work properly again

backend = "xr_glx_hybrid";
glx-no-stencil = false;
glx-no-rebind-pixmap = false;
glx-copy-from-front = false;
glx-use-copysubbuffermesa = false;
vsync = "none";
glx-swap-method = "0";
resize-damage = false;
paint-on-overlay = true;
unredir-if-possible = false;


Note: not all of these are required, I left vsync on and it still fixed the issue
Since glx mode is still broken I will not mark this bug as fixed
