Linux Mint 17.3 on Dell Inspiron 15R with Intel graphics
Short description of error
An object with transparency enabled doesn't clearly show if it is selected. (Cycles render engine mode.) No crash or obvious error, but it's a workflow/usability problem. Makes it difficult to visually determine what is selected without performing some manipulation first to see what moves or changes.
Exact steps for others to reproduce the error
Take an object and enable transparency under object-data, then under settings for the material set the display alpha to a value less than 1.0. An object set like this doesn't correctly show the orange outline in object mode if it's selected while using solid display mode.
