Can't reproduce this on Fenix Nightly 200703 08:40 with or without Webrender.

@haswellready: Can you still reproduce this on latest nightly? If so, could you attach your about:support information?

Still reproducible on my side on Firefox Nightly 200705 06:01 using this link (but intermittent as before):
https://github.com/mozilla/DeepSpeech/blob/d2d46c3aee2f5ea2357628b6614d860bdf748844/training/deepspeech_training/train.py

Test case:

• scroll down until source code with "from"-section,
• swype right,
• swype down,
• then radiply(!) swype left.

Hope it helps.

Thanks @haswellready.

@lsalzman: Looks like this doesn't happen with Webrender.

Hi, @Jessie I discussed with Rares and I will take a look at this bug.
I will update here once I will have the results regarding this issue.

I checked this issue on the latest Nightly build from 7/20 GV 80 with Google Pixel 4 XL (android 11) with Webrender but I couldn't reproduce this issue.
@haswellready: Can you still reproduce this on latest nightly?
I will let my NI until further notice or until we will close this issue.

Still reproducible on my side on the latest nightly build 22010617 on Android 10, Honor 20 Pro.
I dont know how to see my Web renderer.

This is only reproducible on non-webrender and we are working on adding Webrender Mali-G7x support in the near future, which should fix this issue.
