The export feature in Figma doesn’t seem to be working correctly right now. It’s adding an extra pixel to the export size vs. what my Frame is set to; and if I try to export at 2X the size, it doesn’t size up the export. Just adds an extra pixel to the dimension. This wasn’t happening until just now (I export digital and web assets often).
To prevent this from happening, you need to set integer values along the X, Y axes for your frames.
