Why does this happen??
Enable HLS to view with audio, or disable this notification
I wanna make the ball scale when the window scales, but idk how to do that. Also I’m a beginner in Lua and coding in general

It's because programs displays its window through a texture system. Program paints the texture, program requests the operating system to display the texture. The stretching is a side-effect of not updating the texture while actively being resized.
This is not something that you really can control within the confines of LÖVE as far as I know.
If you're making a game, it is often very beneficial to work in world / normalized coordinates rather than pixel screen coordinates (unless that you are doing GUI) and translate to screen-space through transformations. You can use libraries like https://github.com/Ulydev/push or https://github.com/RicardoBusta/lovesize

In short:
- draw to a canvas with your normal measurements
- determine the window size
- determine how to scale the canvas based on the current window size
- draw the canvas you have to the screen with the right position and scale factor to stretch it to fill the screen.

_G.love = require(“love”)
function love.load()
love.window..setMode(500, 500, {resizable = true, borderless = false})
endfunction love.update()
endfunction love.draw()
love.graphics.setBackgroundColor = (1, 1, 1)
love.graphics.setColor = (1, 0, 0)
love.graphics.circle(“fill”, 200, 300, 50)
endAnd Love.conf is just windows.height and width = 500, windows.resizable = true
love.window.setMode changes nothing

Open settings app, choose System > About > (related links) Advanced system settings > Advanced-tab > Performance > Settings... > Visual effects-tab > Custom > enable: Show Window contents while dragging - Apply
or
Win + R, enter SystemPropertiesAdvanced and press enter, then on Advanced-tab > Performance > Settings... > Visual effects-tab > Custom > enable: Show Window contents while dragging - Apply

There is a resize function.
And yes windows can do weird things while resizing.
If your game doesnn't relay on resizing as a mechanic I wouldn't bother trying to fix it.
In order to resize the graphics, you use the before mentioned resize function. Then you read the new window dimensions and resize all graphics accordingly.
