Can you handle fixing this bug by yourself?

Right now I don't know the origin of the bug. I could try. But maybe someone has an idea to go right to the problem!

Which Release Cycle state this refers to? Info for developer.

Pick one option.

Hello @pmaojo
I tried reproduce this issue on Xaomi Redmi Note 4 (Android version: 7.0 NRD90M) but all images are displayed. Please provide more details.

We saw this once on my colleague's phone which is a OnePlus 6 (I believe), also on Chrome. I was able top inspect for a while and noticed this line of css: mix-blend-mode: multiply; on the images. Disabling this line made the images appear. That is all the inspecting I did at that time, and right now I have only 1 Android test device with me which is a Huawei P Smart and cannot reproduce this issue.

So if anyone is able to reproduce this issue on their phone, try looking into that css

Hi @pmaojo @RGijsberts today I was trying to check this problem on 10 different mobile devices (with Android and iOS). I tested on demo and next.storefrontcloud.io, with Chrome, Firefox and Safari (also PWA installed) and.. nothing, everything looks good for me

[pmaojo]

This night I will be able to inspect with my device and try to fix it

[pmaojo]

That is it. Tested with chrome inspector running on my Android Xiaomi 6 Mi. The use of mix-blend-mode CSS property should be avoided. Thoughts:

• An ecommerce should have a guideness to upload their images, there is no need to make the trick to transform white to transparent.
• Remove mix-blend-mode and style background-color white for image placeholder would look good.
• As an starter theme using this CSS property looks like a non standard decision, and many developers will face this problem eventually, may be one of those Android failing browsers is being used by an investor.

Should this be fixed?

In that case, I believe we should have this feature (cutting off the background as an option on the vs-api) level maybe? I mean: we can set the guidelines but the default Magento product set images are not compliant with it - and have just the white background :)

Maybe just some specific blend mode is not supported on the Android? Can You help us checking the different options from: https://developer.mozilla.org/en-US/docs/Web/CSS/mix-blend-mode

?

[pkarw]

This is overall strange as https://caniuse.com/#search=blend-mode shows that it should work on Chrome for Android anyway :(

This fixes:

.product-image--loaded {
    transform: translateZ(0);
}

Cool. Can You Please create a fix for 1.9.1?

[pmaojo]

Yes
