TypeError: undefined is not a function error for iOS devices with Retina displays on 1.18.3

[hoonsubin]

Describe the bug
The same error that was described in issue #84 is still occurring on version 1.18.3. Desktop (including macOS with Retina display) and Android browsers seem to behave correctly, but iPhone and iPad on both Chrome and Safari will show the error exactly on this line https://github.com/matteobruni/tsparticles/blob/7784898e703dc04ae5b7cf7d69a9fb18baece16c/core/main/src/Core/Retina.ts#L51-L56

To Reproduce
Steps to reproduce the behavior:

1. create a react app that imports react-tsparticles@1.18.3
2. copy the particle options from this example https://codepen.io/matteobruni/pen/BaoZBZy
3. start a development server
4. access the development server from an iOS device
5. see the error

Expected behavior
The polygon mask particle effect should be correctly displayed

Screenshots

Smartphone (please complete the following information):

• Device: iPhone, iPad
• OS: iOS 13
• Browser Safari, Chrome

Additional context
As you can see from the screenshot, I have tested from both the template (manually updated the package to be 1.18.3) app and the website I was working on (made with Gatsby), on the same package version.
I was only able to test this using react.
Additionally, the web application that is deployed on a remote server is showing the same issue as well, albeit with a white blank screen right before the particle load instead of any error messages.

okay, I noticed that my iOS device was actually running on iOS 13 and not 14. For some low-level magical reasons, upgrading iOS to 14 fixed this issue for me. I'll close this issue since I think it's been addressed. Thank you for the update.

This problem is still happening for iOS 12 (and lower) devices using react-tsparticles@1.18.8.

I was able to bypass the error by wrapping the code from line 24 to 32 of the Core/Retina.js file inside a try/catch block, but I'm waiting for a proper fix if possible.

Found the issue and tested, version 1.18.9 is now with the fix

[felipefa]

Thank you for such a quick reply, but after upgrading to version 1.18.9 I'm getting this error.

And also this warnings on the console.

I even tried deleting the node_modules folder and installing everything again, but no success. Should I open a new issue?

[matteobruni]

I'm releasing the version 1.18.10 that could fix this issue, this version will be released very soon, let me know if that version fixes this issue

[matteobruni]

1.18.10 is out, let me know if it works

[felipefa]

Yes, it's all working now.

Thank you very much!
