Changing Icon Size from 16 to 32 causes the top toolbar to break and an error to appear


Steps to Recreate Issue

1. Take a screenshot using the Printscreen keyboard button
2. Click "Open with image editor"
3. While editing the screenshot, go to Edit > Preferences
4. The current Icon Size is 16. Click "^" arrow to increase to 32, then click Save.
5. After a few seconds, the application will display an error and the toolbar will be disfigured and turn white and red. Please see screenshot below:

6. When I attempt to dismiss the error, it will appear again until I go back to Edit > Preferences and change the Icon Size back to 16. I also have to restart the application afterwards.
