Acorn on my iMac screen


Using the last release on my iMac , my screen flashes !!!
Any idea ?
Thanks a lot’é


Well that’s super interesting. If you look a still shot of the flash, it’s not the whole screen, but rather it’s the canvas:

Can you tell me if you have a selection on the canvas when the flash occurs? It doesn’t look like you do, but I can’t think of any reason why the canvas would want to all of a sudden change things up.

And one other thing to try- if you open up Acorn’s Preferences, click on “Fussy Stuff”, and change the Renderer: option from Metal to OpenGL, does the problem still occur?
