We have a rather large, and a bit old winforms project that we developed and maintain.
One of our users has started getting scaling issues, where the grids, text, buttons etc are all a bit too large.
I should note that it seems to be just one of the forms (or its child forms) that activates the issue, as when he first starts the program, he doesn't have it. Only upon opening said form, does the issue begin, and "infect" the rest of the program.
Where would I begin to diagnose something like this? Perhaps there is a control that is calling for a different DPI or something?
