delve minimap glitched with graphical artifacts, difficult to read (mac client)

While running Delve since 3.14.1 or 3.14.1b I have been getting glitchy-looking artifacts on my minimap. They vary from manageable to making it very difficult to read the minimap. It seems like the type of artifacts vary by tileset. This is a problem for being able to tell when there are side paths to explore. I have previously had some "static" on minimaps in other areas, but never like this.

no reference number but showing how the corner minimap is very difficult to read with this mess.

no reference but example of a different type of artifact on ice tileset

the "static" here is typical of what I have seen on minimaps before, outside of Delve

Hi. This is still happening.

When you get graphical glitches like this, GGG wants your PC specs as well.

3. If it is a graphical problem, we also need your PC specs
Include Operating System (Windows version), RAM/memory, video card, and anything else relevant.

I would assume that this holds for the Mac client as well.

Here's an example of what the map looks like occasionally outside of Delve. Sorry there's no bug report number here.
