Description fishb8 2006-01-06 04:10:56 UTC
When using the "fade smoothly" transition, the preview works fine, but fails when the actual slide show is running. Bug is present in both 2.0.0 and 2.0.1.

Set to new and change the target.
Comment 3 christian.guenther 2006-01-13 11:29:49 UTC
In my mind the effect also works in the presentation but the performance is bad. Can we made the running effect more smooth so that we can see a fade and not only switching between 2 colors? Please have a look.

@cgu: yes - use DirectX/OpenGL for output (which is currently SO-only).

I saw that this issue was still open, perhaps you could consider using the X Composite Extension on *nix based systems since it is becomming more and more common, and offers very nice transitions without hammering the CPU.
Comment 6 thb 2007-02-05 09:06:53 UTC
@fishb8: well, the composite extension wouldn't really change the game that much - using Xrender should pretty much suffice. Using Xrender from VCL in a way that will speed up this specific effect poses technical problems, though. But there's a cairo-based implementation of the slideshow render backend available, e.g. if you use Debian-native OOo packages. Given a capable driver, this backend is much faster on those transitions.

@thb I'm building mine from Gentoo's portage, and I have the cairo option turned on but it is still dog slow. Am I missing something? Everything is fairly up to date. I'm using OOo 2.1.0, cairo 1.3.10 and a recent nvidia driver.
Comment 8 thb 2007-02-06 09:28:00 UTC
@fishb8: have seen cairo canvas running on top of XGL, also on nvidia hardware. And that seriously kicked ass, I'd say running at least with 30fps. At any rate, cairo is still known to have performance issues here and there, depending on the x server behind it. Did you try the closed-source nvidia drivers?
Comment 9 fishb8 2007-02-07 02:37:23 UTC
@thb: Yes, I'm using the closed source nvidia drivers, and the latest release of xorg-server 1.2. Everything works great, I've even been using Beryl for my window manager for the last month or so. But OOo Impress is still as painfully slow as it was a year ago. I've built cairo with glitz backend... I can't think of anything else. Gentoo's portage doesn't do any serious patching before compiling. There's a couple small one's but they're mostly branding. It's pretty much vanilla. I made the composit extension suggestion because I thought maybe you could render a slide on the secondary buffer and then fade between the two buffers when doing transitions.

@rodo: any other magic/patches you did to your system to make fade run smoothly?
