This return look like it may be an issue?

I saw this and, it just looked like it's too close to the register (via conventional wisdom). I am not sure, however, so I thought i'd ask yall.

Assuming the worst since that's what I tend to see, it probably will be an issue. More assuming here ... we are probably looking at the primary return for an attic installed unit. Since most installers somehow (cost) think any system only needs one return that is probably it. My report would include something like...
Based on the size and proximity of the supply and return registers in the X room, properly heating and cooling this room may be difficult under the current configuration. Any air coming out of the supply register may get pulled to the return before being able to properly circulate and bring the room to the desired temperature. You may need to hire an HVAC tech to re-arrange ducts and registers. I suggest you try the system under various temperatures prior to making a final decision. At the time of inspection, conditions >>>>

It could be an issue, but it depends on the "throw" of the supply register. (throw is the distance the air is moved from the register outlet) To mix the air in the room the supply air comes out of the register between 400 and 600 feet per minute. If you could see the air coming out of the register in the center of the room, it would most likely be hitting the floor and then curl up the walls. The problem would happen in the heating season where the air is more bouyant and would stay near the ceiling level.

It could be an issue if that central return is not in a location that enables it to pull from other rooms. Central return systems often have the most consistant temps in the area they are located and thermostats should be mounted near them.

For crying out loud! Just put one of those plastic curved diverters with magnets on the supply register to aim the flow down towards the floor. The present installation is goofy but honestly, is it really worth it to get crazy on a remedy?

I would point it out and make the same suggestion of a diverter, or how about a ceiling fan?
It is a bigger concern in a new home - bad design, could be other issues. In an old home, it's a retrofit, not expected to be efficient. Buyer's expectations will vary with the age of the home, IMO.
