Description: free implementation of the OpenGL API -- DRI modules
 This version of Mesa provides GLX and DRI capabilities: it is capable of both direct and indirect rendering.  For direct rendering, it can use DRI modules from the libgl1-mesa-dri package to
 accelerate drawing. 
 
 This package does not include the OpenGL library itself, only the DRI modules for accelerating direct rendering. 
 
 For a complete description of Mesa, please look at the libglx-mesa0 package.

Hi @ixemad ,
did you try the deb version?
I asked you in order to know if is something related to snap.

[ixemad]

Hi @debba

I didn't notice there was a deb version. Actually, I can only see .exe, .dmg and .AppImage.

[debba]

It's inside Releases:

https://github.com/debba/tabularis/releases/tag/v0.9.2

[ixemad]

Alright. It's a snap issue.

[debba]

@ixemad Let me know, in order to understand if it's something related to the system or not.

p.s: i added Releases Link in the website, because was missing :)

[ixemad]

Finally, I installed the deb package and everything is working now. Thank you, @debba!

[debba]

Thanks for the feedback @ixemad
I will go in deep for looking snap issues .
