Hi,
I'm running Pd Extended 0.43.4 on Ubuntu 14.04. I've got a Dell XPS13 with Intel Ivybridge Mobile i7 graphics and I'm getting lots of screen tear/flicker when I go full screen with an external monitor attached. It doesn't matter if I'm full screen on the external or primary monitor, I still get lots of flicker.
Attached is an example patch that causes this problem (contains flashing colours)
I've noticed that if I don't go full screen (deleting border 0) then the flicker stops, but I then have the window borders and menu bar being displayed.
Is this a problem with GEM?

thanks for mentioning that this is about Gem :-)
have you tried enabling the "sync to v-blank" (or similar) in the settings for your gfx-card? this will prevent updating of the framebuffer while it is being drawn.

Hi Antonio,
I had the same problem but with an Nvidia card on Mint 15 (ubuntu 13.10).
Imho often times is not a software problem, but a firmware issue with the vertical blank and refresh rate.
Does it happens with movies in full screen on an external monitor?
So not sure this below will help you, but it fixed the issue on my machine:
I put the following lines in "/etc/environment" -
CLUTTER_PAINT=disable-clipped-redraws:disable-culling CLUTTER_VBLANK=True
best, M

Turns out I already had sync to v-blank enabled (through Compiz).
I put the following lines in "/etc/environment" -
CLUTTER_PAINT=disable-clipped-redraws:disable-culling CLUTTER_VBLANK=True
I tried a combination of those two solutions but still getting the same problem

You can check by playing this youtube vidoe:
https://www.youtube.com/watch?v=5xkNy9gfKOg
If you have tearing in general, try to create a file called /etc/X11/xorg.conf.d/20-intel.conf with the following options:
Section "Device" Option "AccelMethod" "sna" Option "TearFree" "true" EndSection
(I assume you have an intel gfx card)
If that doesn't help, try to install compton ( https://github.com/chjj/compton) and run it like this: ./compton --backend glx --vsync opengl
(unless you run another compositor manager at the same time, that should work)

Strangely I'm only getting some tearing as the youtube player controls start to disappear. Once they've gone the video plays as normal.

It might be fine then...
If you have tearing in general, try to create a file called /etc/X11/xorg.conf.d/20-intel.conf with the following options:
That directory (xorg.conf.d) doesn't exist for me
mkdir /etc/X11/xorg.conf.d

That stopped my computer from starting up!
Any other possible solutions?

Upgrade to latest version of the intel graphics drivers, and dependencies: https://01.org/linuxgraphics/downloads
It should be pretty simple. You run a graphical tool which takes care of updating everything.
After that, if you still can't use /etc/X11/xorg.conf.d/20-intel.conf, just put the content of it into /etc/X11/xorg.conf
Upgrade to latest version of the intel graphics drivers, and dependencies: https://01.org/linuxgraphics/downloads
Updated to the latest version but still no file called 20-intel.conf. Not even an xorg.conf. Closest was an xorg.conf.failsafe located in /etc/X11/

Hi, That sounds correct. It's not supposed to be there. Create it, and add the content.

more likely a problem with x11 / opengl / your gfx driver … the following usually works fine for me on my performance boxes with nvidia / intel gfx hardware:
- don't use a compositing window manager - fluxbox is a good choice
- on top of that, start compton¹ with something like compton --opengl --vsync opengl-swc --paint-on-overlay & (off the top of my head - i can look up the exact parameters i am using if you need them)
you still might have to experiment with various driver settings (vsync to which monitor / video output?), but compton seems to be the silver bullet.
hth, t.
¹ - an extremely lightweight compositor, see https://github.com/chjj/compton . the version in the jessy repos works fine for me, don't know about ubuntu.
