Just run into this problem with the Insert slots. Insert names no longer fill the available width of the Insert column. Happens in Mixconsoles and in the Project window mixer too. Resizing columns doesn’t fix it - the broken width also resizes with the column width change.
Only significant thing I changed recently was the Win10/Settings/Display/Custom Scaling which was changed from the default 125% to 100%.
Notice the gap between columns and the cropping of the Insert entity.
