Odd dust concentration pattern on walls, is there a fix? : HomeImprovement

Trying to figure out what causes this and if there is a permanent fix.

I work for my local university housing maintenance, and we have several rooms in our halls that seem to collect dust in a vertical bar pattern on exterior walls. It’s heavily concentrated along the studs and moreso on the screw heads. They are metal studs, so I figured it was a heavy static, maybe a grounding issue, not sure. Looking for any and all ideas, or if someone actually knows how can I deal with it? Is there a permanent solution, or do we just keep painting over it ever other year?

Trying to link pictures, not sure if it’ll work, I’m new to reddit
