Pepper Flash Plugin no longer works after update to v0.13.0 (Linux)

[CliqueBait]

Pepper Flash Plugin no longer works after update to v0.13.0.

I tried repeating the troubleshooting steps from the wiki but to no avail.
Reverting back to v0.12.15 works just fine.

I'm going to go back to using v0.12.15 for the time being but feel free to ask me to test any possible fixes.

Name Version
Brave 0.12.15
Muon 1.4.31
libchromiumcontent 53.0.2785.143
V8 5.3.332.47
Node.js 6.5.0
Update Channel dev
os.platform linux
os.release 4.8.0-34-generic
os.arch x64

I notice the same thing on Windows 10 64 bit on http://hulu.jp

I see allow notification on http://hulu.jp on Win 10 x64 with flash enabled (browser upgrade from 0.12.15 to 0.13.0)

@srirambv yes I see it too. Please continue to play a stream and see if it is played successfully

This started after I followed the instructions at https://superuser.com/questions/1094597/enable-user-namespaces-in-debian-kernel#1122977 to enable user namespaces to avoid having to start with --no-sandbox.

Seems starting with --no-sandbox solves this. Not ideal at all though... From what I can tell nothing wrong with the permissions on the file

Can confirm. This bug is still present in Brave. Trying testing every new release but still is not fixed yet.
Last test made on:

Brave | 0.19.35

V8 | 6.1.534.41

Update Channel | Beta
OS Platform | Linux
OS Release | 4.10.0-35-generic

Flash files in /usr/lib/pepperflashplugin-nonfree/ . Flash enabled in options but sites not detect it even when I allow to use it.

Look at last three lines.

Also looks like above solution from @geekgonecrazy to launch brave with --no-sandbox flags just work and flash starting work correctly.
