D11722: If GL context creation fails fall back to the software renderer

[Kai Uwe Broulik]

broulik added a comment.


  I like the direction but I would like
  
  - something that doesn't permanently lock out the user if something failed once, we either need a KCM like KWin has or a SNI ("we had to switch you back to software rendering" with a sad puppy face)
  - something more generic in KDeclarative like QtQuickRenderSettings so stuff like KRunner, lock screen and so on can do the same, especially the screen locker should fail gracefully

So you will permanently force software rendering even for a single hickup (think of upgrading nvidia driver)?

Add period after fallback
