Shadow artifacts and color distortions when using compton(1). Perhaps after recent Xenocara update?

Erling Westenvik-2
Hi,
After upgrading to todays snapshot (February 10th) I experience some rather
ugly shadow artifacts and color distortions when using compton(1) under cwm(1).
It may perhaps best be described by linking to an issue report from April 2018
at github:

https://github.com/chjj/compton/issues/487

and from that page - a link to a screendump showing exactly what I experience:

https://framapic.org/dHfk2217huGs/NIiGKJsfnz52.jpg

The problem can be reproduced by specifying "glx" as backend in compton(1).  It
appear to have been major glx-related imports in Xenocara on January 29th 2019.
My previous snapshot was older than that, perhaps as old as from December 2018,
but for certain newer than the previous bulk import which appears to have
been October 23rd 2018.

My graphics card is a ATI Radeon HD 5770. Dmesg below.

Not sure how to attack this. Help/ideas appreciated.

Regards,

Erling

Yep, I noticed the same with compton after the update to Mesa 18 in snaps. I
think the following GitHub issue is actually the more fitting one:

https://github.com/chjj/compton/issues/477

For me, switching to xrender backend for compton is a satisfactory solution
until the freedesktop bug referenced in the above link [1] has been addressed.

At least for me that comes with a huge performance penalty, and I cannot
have blurred transparent backgrounds. All right, so it's just eye candy,
but I find the ability to have a certain sense of visual depth really
helpful.
