st: Don't try to create shadow for empty texture (1.05 KB, patch)

Description Hussam Al-Tayeb 2017-06-29 16:21:09 UTC 
I see this warning in my journal when starting applications.
Jun 29 19:15:52 hades gnome-shell[28955]: _st_create_shadow_pipeline: assertion 'src_texture != NULL' failed
This warning only happens once per application after logging into Gnome.
For example, opening gedit from gnome-shell results in this warning. Closing Gedit and reopening it does not show the warning again.

However, if I close all applications and alt-f2 -> r, the warnings will start showing again.

Even though the API documentation doesn't say so, the underlying
Cogl texture of a ClutterTexture may be unset, so check for that
case to avoid a runtime warning.

Hi Florian. Thank you very much. That cleared the warning.
