I have been using Sprite Blend Factors to do some color effects and its been working as intended until i tried out my game in ios 14 beta. Im using DST_COLOR for the source then DST_ALPHA for the destination to create a sort of spotlight effect.
here is a video of it should look (running in safari ios 13)
and this how it looks in IOS 14, noticed that the blending is different already and when i change orientation/window size, the blending starts to flicker
I believe this an issue with the new IOS and might be fixed by them but i would like to check it here if there is any solutions for this. i have tested this with 2.2.2, 2.4.2 & 2.4.3-rc3.
