If you adjust the size of the output view when running your code, you will see a white line appear next to the whole of that section in the split view.
Could you please provide example code that is as simple as possible (copy and paste should allow you to send it here) of this bug?
No I don’t believe this bug requires any sample code. It’s a white line that appears along the output window if you adjust size while playing the project. Will look into it – thanks!
