Chargrid HiDPI Scaling Fix

November 09, 2020

I spent some time over the weekend trying to reproduce a bug where winit windows end up the wrong size due to rapid scaling factor changes. Ultimately I couldn’t reproduce the problem (but I’m keeping an eye out) but what I did learn is that when the mouse cursor is on the hidpi monitor (I have two - one hidpi and one normal-dpi), and a windows opens on the non-hidip monitor, it starts with the hidip scaling factor, but soon after starting its scaling factor changes back to 1. I found that chargrid_graphical wasn’t handling the scaling factor change (only the accompanying window size change), which caused graphics to appear blurry after the resize. It’s now fixed.
