System Information
Operating system: Gentoo Linux
Graphics card: AMD VEGA10

Blender Version
Broken: Latest git version

Short description of error
When playing back animations in the viewport there is a memory leak in the drawing code it seems.

Exact steps for others to reproduce the error

Download and open the attached .blend file
Switch the viewport to "material preview"
Playback the animation
Notice that the memory usage keeps growing.

If Blender is compiled with ASAN this is one of the reported memory leaks:

Indirect leak of 14880 byte(s) in 620 object(s) allocated from:

Note that there are some seemingly unrelated asserts from the the custom data layers.
@JacquesLucke and @HooglyBoogly can you guys look into the asserts?
They are probably unrelated to the memleak, but I don't think our production files should trigger asserts if everything is fine.
