Maybe it has something to do with OpenGL Off-Main-Thread Compositing (https://wiki.archlinux.org/index.php/Firefox_tweaks#Enable_OpenGL_Off-Main-Thread_Compositing_.28OMTC.29) that is not used with flash ?
This should be reported to Adobe.

Ever confirmed: true
Summary: Flash video tearing → Flash video tearing with enabled "unredirect fullscreen windows"
Ideally we should encourage sites to move away from Flash video.

It happen but very slowly !

What I don't understand is that HTML5 videos don't have tearing (with OpenGL Off-Main-Thread Compositing enabled) whereas Flash do. If Flash videos was rendered the same way as HTML5, with the OMTC feature, they shouldn't have tearing.
So, no interest for this ?
Can this be related to OpenGL Off-Main-Thread Compositing (https://wiki.archlinux.org/index.php/Firefox_tweaks#Enable_OpenGL_Off-Main-Thread_Compositing_.28OMTC.29) that is not used with flash ?
Thanks !
I know that Flash is on the way out but can this be fixed please ?
Thanks !
I still hope that can be fixed. Flash is still not dead and since it work with html5 there is no reason to not make it work with flash too.
