[Solved - Graphics Driver Bug] Weird Canvas Issue

[BOT-Brad]

I was testing in Mac OS X before - after booting into Windows it seems my AMD Radeon 6750m has the same graphics driver bug.

It happens for me regardless of whether I use 64 bit or 32 bit versions of 0.9.2 or 0.10.0 though.

Ah yeah you are correct, I just realised I was using the edited version with the filled rectangle method by mistake.
Nevermind, I presume the workaround (setColor & fill) is ok? Not noticed any other issues (And I have been dev'ing on this PC with this GPU for about 6 months in LOVE 0.9.0 & 0.9.2)

Yeah, that'll do as a workaround - although performance might not always be as good. To make sure it has the best possible performance when doing that, set the blend mode so that it won't do any blending: love.graphics.setBlendMode("replace", "premultiplied")

You could also probably do something like this, which I believe should work as well:

Code: Select all

function clear(...)
    love.graphics.points(0,0)
    love.graphics.clear(...)
end

Yeah that is essentially the original workaround I found regarding draw anything else to the canvas and it works. Weird one that, but thanks slime.

I plan to have a workaround in love itself for 0.10.1, for affected systems.

Ooh, very nice. Great work all around, keep it up.
