Gfx clutter during video playback

[NilsNojje]

On RC3 there is gfx clutter over and under the video during playback. If you toggle the playback menu, the region does not clear and traces of the menu remains on screen efter hiding it. Also subtitles does not render properly here and are suffering of the same issue.

Wondering if this isn't a XBMC bug instead of a XBian one?

[rikardo1979]

other distro are OK so it's XBian

[popcornmix]

@NilsNojje Are you sure you haven't enabled non-default dirty rectanges? http://wiki.xbmc.org/index.php?title=HOW-TO:Modify_dirty_regions

For GL ES platforms algorithmdirtyregions should be set to 3. 1 and 2 will produce artefacts.

[CurlyMoo]

That could be the issue because by default XBian RC3 has the algorithmdirtyregions set to 1.

[NilsNojje]

Testing was done on a fresh install. Only changes was localization and turning on hdmi passthrough for audio decoding.

Will try setting to "3".

[rikardo1979]

OK, have tried to change it from 1 to 3 and now I have no proper HDMI output, the picture is just flashing on remote presses or spontaneously so cant even see the GUI. Tried to reboot and its same

[NilsNojje]

Tried now changing to "3". Playback works with subtitles and playback menu, but the main GUI when just browsing menus and such, blanks out to black all the time. It pops up when you press a button, but goes back to black after a few milliseconds.

Edit: I started playback with the iPhone remote and that works well, but using the GUI is not possible.

My advancedsettings.xml --> http://pastebin.com/3cqabciJ

Were there any other non-default advancedsettings in the section?

I have also noticed that the CEC remote acting bad since the update. it has the multi press issues on single button press

[popcornmix]

I'd say remove:

<gui>
<nofliptimeout>1000</nofliptimeout>
<algorithmdirtyregions>1</algorithmdirtyregions>
</gui>

(nofliptimeout is zero by default).

<useddsfanart>false</useddsfanart>

is a default setting, so should be removed.

I'd suggest:

<cachemembuffersize>20971520</cachemembuffersize>

is removed too. If not present it defaults to 20M on a 512M Pi and 2M on a 256M Pi.

[rikardo1979]

@popcornmix thanks m8 removed suggested lines and it seems to fixed the issues havent touched cachemembuffersize yet but rest seems to be working fine even the CEC remote working as it should

Nice catch ;)

[CurlyMoo]

@popcornmix, can you do a pull request on the advancedsettings.xml?

[anaconda]

As far as I know these were needed for the CuBox-i/HB. But we really should kill -xbianhome and ship an appropriate advancedsettings.xml in -xbmc packages (in system/).

[NilsNojje]

Applied all changes that @popcornmix suggested and I can confirm it's working fine again.

[CurlyMoo]

@anaconda: agree. We should also limit these pre-installed files to the ones we actually changed and let the rest be installed by xbmc.

[CurlyMoo]

I've updated the RC3 image with this fix. If @anaconda and @mk01 can then fix the packages.

[nicolalorusso]

@popcornmix: you win. I have just commented out the GUI section and all works fine. Thanks a lot.

[anaconda]

@CurlyMoo can you please test nofliptimeout -1 and algorithmdirtyregions 1 on a CuBox-i/HB?

[CurlyMoo]

Doesn't really matter, the conflicting RPi settings also work fine.
