Alek hardcoded the size of OSBOT. So the way I fixed that by using this method
Open OSBot
Open task manager
Find OSBot's App
Right click on OSBot, and select "Open file location"
Look for "javaw" and right click on that.
Select from the menu "Properties"
Look for Compatability in the new window
Looks for "Settings" and then change the box saying "Override high DPI scaling behavior scaling performed by"
Use the drop down menu, and select "System"
That's what I used following a video, but I can't find the video, and that's on a Windows 10 laptop ASUS Zenbook.
