Canvas.ClearRectangle is clearing literally everything

Syntec

I am not even sure how this is possible, but Canvas.ClearRectangle now clears EVERYTHING including the window behind lol
200X200 Canvas on Window 1 (which has a white background)

g.Opacity = 0.5 # This was for testing if the initial results where due to a bug with opacity settings, it is not.
g.DrawingColour = Colour.RGB(255, 0, 0)
g.FillRectangle(0, 0, g.Width, g.Height)
g.ClearRectangle(25, 25, g.Width - 50, g.Height - 50)
g.FillRectangle(50, 50, g.Width - 100, g.Height - 100)

Expected behaviour is 200X200X25 red square, with a smallr 100X100 solid red square (square bullseye)
Actual result is below... it literally obliterates everything through the window... that is this objo forum post through the new window in my window.

This is an Objo regression, not anything you're doing wrong. Sorry.

A recent fix made ClearRectangle genuinely erase pixels, but a Canvas without a Backdrop is currently drawing directly onto the window’s rendering surface. Consequently, clearing the Canvas also makes that part of the window transparent, allowing whatever is behind the window to show through.

The Opacity setting is unrelated to the problem. Your ClearRectangle usage is correct.

Thanks for catching this. It's fixed for the next release: https://feedback.objo.dev/bug/1234
