[Bug 1100456] Re: Every screen change triggers full screen XDamage event
I don't know why this bug has been marked as invalid. Every screen change triggers full screen XDamage event This is exactly what happens and it didn't used to be this way. I run software that depends on damage events and it has now ground to a halt. Yes, a damage event doesn't mean that every single pixel within the area has been updated, but there's a big difference between a little margin for correctness and just invalidating the entire screen all the time. Frankly, I've had it with whatever compiz quirks get introduced with every new version of Ubuntu and I've switched my WM to KWin. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1100456 Title: Every screen change triggers full screen XDamage event To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1100456/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1100456] Re: Every screen change triggers full screen XDamage event
Hi there, reading the comments and having issues myself that seem similar to this bug, I tried enabling the 'Show Repaint' plugin. I soon as I activate it, my whole screen is constantly blinking: full screen receives a pink overlay then some small area receives the pink overlay once out of three (subjective feeling). And that's without touching the mouse nor typing anything. Let me know if there is some way for me to provide more information. FTR, since I upgraded to quantal, the dash became very slow even when I login. It then becomes slower and slower and I usually need to login/logout every day to restore some usability. About this computer/Graphics says: Driver: GeForce 7300 GT/PCIe/SSE2 Experience: Standard Cough, I hope that's not the standard experience ;) And I can see it's specific to this desktop, my other one is slower but still usable. Unfortunately, the other says Driver: unknown -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1100456 Title: Every screen change triggers full screen XDamage event To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1100456/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1100456] Re: Every screen change triggers full screen XDamage event
Vincent, This bug has been found to be invalid as discussed above. That is still true unless your full screen blinks constantly. If the full screen is pink or coloured then that is not a problem. That's normal for Show Repaint. It has to be /changing/ colour to indicate redraws. First thing to check is that you don't have a fullscreen/maximized window behind everything that is redrawing constantly. So close all apps. Does it still happen? If so then please take a video and attach it here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1100456 Title: Every screen change triggers full screen XDamage event To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1100456/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1100456] Re: Every screen change triggers full screen XDamage event
I can't see any bug in your test program right now. But I also can't explain it. If the root window was constantly getting damaged though, Show Repaint would be flashing the whole screen and Compiz' CPU would be higher. I see two possible explanations: 1. A bug in your program (which I can't see) 2. Compiz is choosing to ignore damage to the root window (which I doubt, because it does smoothly respond to root window redraws) Both seem quite unlikely. Maybe there's a third explanation... ? ** Project changed: unity = compiz ** Also affects: compiz (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1100456 Title: Every screen change triggers full screen XDamage event To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1100456/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Actual results: XDamage @ x=0 y=0 - 1366x768 OpenGL applications always post full-screen damage whenever they call glXSwapBuffers. Just because you get getting a fullscreen damage rectangle reported when using XDamageReportRawRectangles, it doesn't necessarily mean the whole screen got redrawn. Think about it, if libGL needs to calculate and post the damage region to the server, how is it supposed to figure out what regions of the image changed when it gets told that the pointer to the image itself changed. For all OpenGL cares, the new buffer is completely different to the old buffer, because the new buffer always starts out in an undefined state, so it could be anything. Having a full-screen damage region is just another way of telling clients I have no idea what the contents of this window are going to be. Which is about accurate. It doesn't actually ask the server to redraw the whole window. When you draw directly to a double-buffered root window, its effectively the same as the monitor scanning out the pixels from the buffer you're drawing into. So changing the pointer is a very inexpensive operation. It sucks if you're either a compositor or a VNC app. For VNC apps - that's life: OpenGL simply can't know what the contents of new buffers will be. For compositors: thats why we have full screen window unredirection.

To clarify some important things: XDamage on the root window != screen redraws, especially with hardware overlays XDamage on the root window != compiz damage.
