Alpha channel ingored

I have a game that uses 12 canvases with transparency however when using blendmode replace to make an area of a canvas transparent again I get a black flashing (no vsync) which appears to be caused by the alpha channel being ignored. When I do a lot of drawing (alpha blendmode) the alpha channel is completely skipped on both the canvases and other things drawn. However when I only use 7 canvases there is no problem.

Not really. I don't see why that would be necessary. The problem as far as I can tell must be in love.graphics, love.windows or the graphic drivers. When I get access to my code again I'll do one more check to see if it could possibly be a problem in my code.

You must provide some code if you want any help with such issue. Else if you are convinced that it's an engine bug, go to the bug/issue tracker and post there.

You should post code to reproduce the issue no matter where you think the bug is coming from, otherwise other people won't be able to help.
