I know this code isn't very good. Just kinda a prototype at the moment. I want the rectangle to keep up with my mouse cursor. Currently, the rectangle that is being rendered is lagging behind the cursor.

Lagging how?

#

uhh, rather than the end point of the rectangle being at the cursor, the rectangle is being drawn slower than the cursor moves

#

the specific function is takeUserInput()

An input lag of a frame or two is normal.

#

its much more than a frame or 2

#

#

#

#

it was a bit worse before using XFlush, but i can't figure out how to fix the problem as a whole

Making an event loop in a different program with a simple window has the correct functionality but the problem is that I am clearing the window every time I am redrawing the rectangle. I don't think I can clear the window each time because it would clear the SCREEN_IMAGE that i overlayed onto the overlay_window

#

currently what I am doing is re-overlaying the image every time and I believe thats my problem but I dont know of another solution to keep the image shown
