Text editor extremely glitchy on mobile (Android)

Hello, I’ve been using sharplab.io on mobile for a while now, and I’ve noticed it’s very difficult (and annoying) to use it there unfortunately, as the text editor seems extremely glitchy. This is due to it doing a few different things pretty often:

• Have the cursor jump back, resulting in you writing a word with jumbled up letters
• Randomly deleting characters (eg. you’d type bool a and it’d delete the a identifier)
• Have the cursor get stuck between lines when quickly deleting characters
• Have the text editor type your code back again after deleting it (?!)

Here’s a GIF I recorded that shows the first two issues. You can see the full recording here, which also shows the IL output window as well as the individual keys being pressed on the keyboard.

And here’s another that shows the other two issues:

The text editor is already not perfectly responsive on mobile, but that’s secondary, these issues instead really make you have a hard time trying to write some code on it.

Hopefully this is not something too difficult to fix, thank you again for your hard work! 😄

Sure, you can try it now, but I can promise a lot of bugs:

Hey @ashmind - thank you for the quick reply! I wasn’t aware those were all already known issues in the code editor you’re using, glad to hear they’re already being tracked there though and that they should be fixed in the new version. I’ve seen the new CodeMirror 6 release and looks like it’s going to be pretty great especially for mobile, so yeah if it’d be possible to have an opt-in to a preview version of that it would be amazing! 😄

Thank you again for your work on sharplab.io! 🍻
