Returning user needs help updating older models with obsolete parts

[Roland Melkert]

every single part... wow. We did some updates, but not that much. Could also be a configuration problem. Can you share a screenshot?

Indeed,

also having white outlines isn't an obsolete indication.

It's the alternative selection / hot tracking method.

If you didn't enabled that it could indicate an OpenGL problem as it is the fallback method if the conditional line shader failed to load.
