This happens on the HP Slate 21. ( NVIDIA Tegra4 )
Firefox for Android version 42 did not exhibit this problem.

Hello,

I was unable to reproduce the issue that you have mentioned. In Comment 1 you have said that you are using Firefox for Android version 42, Firefox is currently at version 61 as the version that you have set.

Could you try updating your version of FF and see if the problem still persists?

Thank you!

Hi, firstly, please retry on the latest version of Firefox(Nightly or Release). 
To send a photo you need to click on the 'Attach file' just above the comment 0 (your description). After that, you need to click on the 'Browse a file' and chose your attachment. I'll wait for your update, thanks.

Hi Stefan,
Thank you for the attachment help.
Firefox is the latest release version ( 62.0.1 )
Please note that the same "garbled canvas" problem exists in Fennec.
Please also note that this problem started a long time ago, I think after FF42.
If you wish, I will try to find exactly at which version it broke.
Thanks & regards.

Thanks for your update.
Tested on the latest version of Firefox Release (62.0.1) and Nightly (64.0a1 from 2018-09-13) with Samsung Galaxy S8 (Android 8), Motorola Nexus 6 (Android 7.1.1), LG G4 (Android 6.0.0), also tried with Samsung Galaxy Tab S3 (Android 8) and Sony Xperia Z2 (Android 6.0.1) and can't reproduce it. Can you send us a logcat to investigate where the problem occurs?
