Browser issue Crashes in the new thread form on mobile

[CyberAP]

Affected version

Beta 4

When using both quick and regular new thread form the whole screen freezes and stops reacting to touches, later it goes partly black and blinks. Probably gpu running out of memory. This could be just my device though, trying to replicate this on other sites, no luck yet.

OnePlus 3t, latest Chrome, Android 7.1.1.

Trying to find a cause for these freezes. From desktop performance analysis it seems like every time you type a letter there are multiple new nodes created, so after writing 2 lines of text node count increased from 3946 to 5783.



Almost the same story from mobile performance snapshot:



See these 2 straight lines in JS Heap? These were the exact moments when the phone froze for a couple of seconds but was able to free up some memory and reestablished reacting to touches, it also brought back the keyboard which ran out of memory and crashed. The keyboard I am using is SwiftKey.
One thing I am not sure about is why the node count dropped later on, this did not happen on PC. Also on mobile the page feels very unresponsive and slow if you type 6-7 lines of text.

Any change if you switch to the stock keyboard?

Same.

Just to confirm, do you see similar behavior with a "basic" Froala setup? https://www.froala.com/wysiwyg-editor (That's also using a slightly newer version though nothing explicitly mentioned there about performance.)

Yes.

Just tested this on XF1, same thing. I think I figured this out, if I switch to Russian this issue goes away, so apparently it has to do with spelling autocheck. If I write in English all the text is marked red, no matter what, now I have to find out how to disable that.

I've disabled spellcheck in Chrome flags, the issue is now gone.
