pepperflashplugin stable vs. developer

  • hi @all,

    i'm reporting a rather peculiar issue concerning the flash plugin on debian linux. both the opera-stable (26.0.1656.32), and the opera-developer (27.0.1689.22) packages are installed, dpkg reports version 1.8 for the pepperflashplugin-nonfree package.

    it all started a few days ago when i was watching a video on youtube, and when i suddenly noticed that my computer was stopping to react on input. first i could switch to a terminal window and issue the command "killall -9 opera", but acting upon this seemed to take ages, and after a short while the whole system was frozen completely, except for the sound from the video, which was still working unimpeded. the only thing i could do was a hardware-reset.

    after this reset the pepper plugin plays videos (images & sound) only in the developer version of opera, the stable version is giving me just the sound with a blank black patch where the video should be running. it does not react on any input, thus giving me no chance to activate the plugin's configuration menu.

    the plugin is of course the very same for both versions of opera, i've checked that. i've also compared each and everything in the experimental opera://flags of the two browsers. i've "dpkg --purge"d and reinstalled both the opera-stable, and the pepperflashplugin-nonfree packages (the latter with a complete new download of chrome from google), still the misterious behaviour persists. and still only in opera-stable.

    something clearly has happened, but what, and where? and what can i do?

  • edit: perhaps i should mention that in the stable version i've enabled hardware acceleration with 4 raster threads, whereas in opera-dev hardware acceleration is disabled. but the config changes in stable i had made some time before the "crash" happened, and i'm pretty certain i had restarted the browser after that.

    and maybe i should also mention that i'm running jackd, version 5.

  • no reaction, nothing at all? not even questions, no further details asked for? that's rather poor for a performance, isn't it? could someone from opera at least have the goodness to inform me about when someone will look into the issue?

    because it's quite cumbersome to always switch between two browser versions, or to keep everything up to date in both of the two (or to remind myself always in which version i currently am, when i'm looking for a bookmark and can't find it.)

  • no reaction, nothing at all? not even questions, no further details asked for? that's rather poor for a performance, isn't it?

    This is a user support forum. Employees such as myself drop by but it is not guaranteed. If you have a bug you should report it to:

    Even there you are not guaranteed a response. Opera is a product used by millions and therefore we cannot give a personal reply to every person that asks a question.

    That said, try running with a clean test profile and see if it works there:

    opera --user-data-dir=$(mktemp -t -d opera-test.XXXXXX) &
  • opera --user-data-dir=$(mktemp -t -d opera-test.XXXXXX)

    with that it worked, though i got two probably unimportant messages in the terminal:

    MESA-LOADER: could not create udev device for fd 12
    ATTENTION: default value of option force_s3tc_enable overridden by environment.

    (i didn't mean to be rude, please accept my apologies.)

  • Ok, if it works in a clean profile but not your main one I would assume it is something special about your main setup. Do you have any extensions installed? If so try disabling them and see if that helps.

    (i didn't mean to be rude, please accept my apologies.)

    No problem, I do understand the frustration!

  • Do you have any extensions installed? If so try disabling them and see if that helps.

    no effect. apart from this, i have the same extensions installed in both browser versions: adguard, classic images, classic tabs, ghostery, internal pages.

    my theory is that there exists some file (or a corrupted file, for that matter) somewhere which normally would have been removed or closed in a normal shutdown procedure of both the plugin and the browser. this removal or closing couldn't take place a) because the system was (or at least appeared to be) frozen, and b) because of my manual resetting the hardware.

    the fact that in a clean profile the effect does not appear corroborates my theory. the funny question now is: which file amongst the myriads in a normal user profile might that be? i'm neither familiar with "find", nor with "diff", but if you could provide me with a oneliner i could use, i would try to compare the resulting outputs for the two profile directories. (i haven't shut down and rebooted the system since then, but always sent it into hibernation, hence the test profile still exists in its pristine state.)

    however, there's probably a simpler solution.

  • i think i got something that might be of help. i started both versions of opera from the shell:

    opera --disable-gl-error-limit 2>opera-stable.log


    opera-developer --disable-gl-error-limit 2>opera-developer.log

    both browsers report html parser errors from the speed dial page. ;)
    then the developer version's output ends with:

    [WARNING:flash/platform/pepper/pep_module.cpp(63)] SANDBOXED

    not so the output from opera-stable. first it reports:

    [1223/] [.RenderCompositor-0x3fb4d035b900]GL ERROR :GL_INVALID_OPERATION : glTexStorage2DEXT: <- error from previous GL command

    then the above sandbox message appears, after that the log says (twice):

    [1223/] WebContentsDelegate::CheckMediaAccessPermission: Not supported.

    and then i get streams of error messages always repeating something like:

    [1223/] [GroupMarkerNotSet(!:D0D47B24E13F0000]GL ERROR :GL_INVALID_OPERATION : ScopedFrameBufferBinder::ctor: was unhandled

    and so on. i can send you the whole log if you give me an address. you'll find mine in your database, i trust.

    happy holidays, btw. (this time i'm not awaiting a swift answer. :D )

  • from this discussion i am learning that there exists a built-in task manager. obviously this ominous thing might help. how can i access it? should i install a dbg-version?

    questions over questions, i know... ;)

  • just with the purpose of bringing this issue back to opera's attention (meaning that i'm still in hope someone actually cares about it):

    (1) i removed the whole .config/opera-stable/ directory, only the files connected with my browsing history (cookies, history, stash, and so forth) i first moved out of the way. then i forced dpkg via mc to re-install opera-stable and opera to create its .config directory from scratch.

    (2) i modified the opera://flags so that hardware acceleration is enabled.

    (3) the problem persists. i get the audio, but a black rectangle where the video should be.

    here's what the opera://gpu summary says:

    the problem clearly starts at line 1909 in, because this is what the first error messages states:

    that's all i can do for you gays, short of dropping my pants. but for that i first might want to get to know you better. ;)

    any suggestions on how i can circumvent things without disabling hardware acceleration?
