wrong crop on 1st browserstart on mobile

[indyger]

Hi folks,

i've have a problem with cropping images and i don't know, how to solve it. I try it since several days and don't get it. Maybe, you have seen a strange behavior like this already and can give me a hint.

I wrote a little PHP-Script, which crop id cards for me. Everything works fine with one exception. When i start the webbrowser on my mobile phone for the first time (or close it and restart it), the 1st crop is very badly cropped. Then, i crop the 2nd image and it works perfectly until i restart the browser again. I researched this on some phones and browsers an got the results in the attachment to this post.

Has anybody an idea, what the heck this is xD?

Best regards and have a beautful day!

How about some other mobile devices?

Thank you for the answer. It don't know, what i should answer to your question, i'm sorry. The same Discusion is in issue #1036 active btw.

I (and the other posters) can reproduce it on android devices. Apple devices seem's not be affected. It occours also in your "official demo site", so we can say, it's (i think) not a bug by implementing die cropper in different projects.

Here are steps to reproduce the error every time:

1. open new tab (in Brave oder Chrome Browser in my case)
2. open your Demo Site
3. Click button "Get cropped canvas".
4. You get an bad cropped image.
5. Click on close
6. without reload the tab or anything, click again "Get cropped canvas"
7. you get a perfect cropped image

Best regards!

I attach 2 screenshots. Maybe their is something misinitialized?

After a break, i wanted to retry to fix this issue and i can't reproduce it anymore on Chrome. Some days ago, a chrome-android update was released. So, on Chrome, on every of my mobile phone, it workes like a charme. On Brave, with the same chromium version, the bug is active. Really strange.....
