Bed and chests turn transparent if no entities are present on the screen

the following blocks turns transparent :

• the edge of item frames
• bed
• chests ( trapped , regular , ender in both single and double form)
• the book of the enchanting table
• the conduit
• the bell
• sign (but only without text)

 

i tried several situation but it seems that as soon as an entity is present on screen it nullify the bug (seen here as the arrow)
