Just noticed that the left one looks a little bit darker here. However, the interesting thing is that the same is true for native LÖVE as well.Nixola wrote:It looks fine here; Linux x64, Firefox (latest), Intel GPU (up to date drivers).
Haha, that's cool indeed. Well, there's certainly something wrong with that ParticleSystem/Canvas combination.Ulydev wrote:Here's what I get on a Macbook Pro with Intel Iris GPU
See the notice near the top of the [wiki]Canvas[/wiki] wiki page. tl;dr: use love.graphics.setBlendMode("alpha", "premultiplied") when drawing the Canvas to the screen, if regular alpha blending was used when drawing content to the Canvas itself.pevzi wrote:There seems to be a problem with ParticleSystem drawn to a canvas. It is rendered correctly when drawn directly to the screen but when I try to render it to a canvas and then draw the canvas to the screen, it looks nothing like intended. Here's an online example and here's the source code for it.
Oh. Totally missed this one, thanks. It fixes the issue with the canvas being drawn darker but it still doesn't work for me when using love.js with Intel GPU. Just getting the same result as before. I've updated the example.slime wrote:See the notice near the top of the Canvas wiki page. tl;dr: use love.graphics.setBlendMode("alpha", "premultiplied") when drawing the Canvas to the screen
That sounds like a graphics driver bug. Which Intel GPU do you have? Are you using the most recent possible graphics driver version for it?pevzi wrote:That's interesting. Here's what it looks like in both Chrome and Firefox when using Intel GPU: But it works fine when I run the browser with a discrete NVIDIA GPU.
I use Windows 10 x64 with the latest 64-bit Chrome and Firefox.
I thought so too but I've just asked my friend who uses AMD GPU to test this and it looks like this for him as well.slime wrote:That sounds like a graphics driver bug.
Intel HD Graphics 4600 and yes, I have the latest driver version installed.slime wrote:Which Intel GPU do you have? Are you using the most recent possible graphics driver version for it?
