Comment 14 for bug 1661093

@Pat, Its seems you got to the root of issue.
"short version is that disabling a certain Mesa plugin lets it run without issue (once apparmor is disabled):
MESA_EXTENSION_OVERRIDE="-GL_EXT_bgra" webbrowser-app"

There seems to apparmor issue definitely with webbrowser-app, There has been few bug reported with apparmor issue, I would be happy to check this,

I checked syslog.txt, Which is trimmed one, and with initial look none of denial looks to be problem, So just to be sure I need full version of syslog. Could you give me that?
