GP Beta Test Forum

filled whole screen whereas I expected it to just fill the circle

Thanks for reporting this.

I've reproduced it. WIll fix.

JFI The other fill functions do unexpected things as well

This bug is a bit strange. The fill example works the second time, so there is some initialization issue I don't yet understand. Do the other cases also work correctly the second time? If so, this is all caused by the same bug.

I am experiencing repeatability issues with several drawing functions not just this one

And this one gives wierd result - seems to be drawing something within the sprite image rather than the canvas

aah - the penny drops!

The Drawing and Pixels blocks refer to the image of the instance not the canvas :)

Still doesn't seem to work for me in V072 Win10

Interesting! The bug is fixed on other platforms, but not Windows. There's apparently a difference in the how Windows reads textures into bitmaps.

In other words, this bug arises from a low-level implementation issue. GP tries to make things work exactly the same on all platforms but sometimes something subtle slips through.

As a workaround, this works as expected if you set the pen color to any color except pure black. For example, (gray 1) will work and is basically black.

I might might make (gray 1) the default pen color as a workaround. :-)

Make it the green one that you use as default option in all the colour ops and then no-one will ever know :)

Until they draw a black circle of course :)
