Solution to image viewer not opening pictures & showtime not opening videos

I use bluefin stable.
long story short :
I fixed it by adding GSK_RENDERER=gl to /etc/environment then I sourced /etc/enviroment
by running the following commands

1-sudo nano /etc/enviroment

then added GSK_RENDERER=gl & saved the file

2-source /etc/enviroment

then rebooted the system


the details :
image viewer & showtime fail to open files & even open at all

opened logs
opened logs & there are three messages related to them

first one :MESA-INTEL: warning: …/src/intel/vulkan/anv_formats.c:794: FINISHME: support more multi-planar formats with DRM modifiers

second one:WL: error in client communication (pid 8004)

third one:Error 71 (Protocol error) dispatching to Wayland display.

I searched in google for these log messages & applied the workaround .

the the following post helped me so much
