water plugin not working

[einheitlix]

Hi,

I've been trying to get the water plugin to work on my Beryl desktop, but it turns out this is harder to master than I had expected. Upon activation of the water plugin in the beryl settings manager, when I try to activate e.g. the Rain using Shift+F9, nothing at all happens.

I noticed that Beryl complains about some glx extension that is missing:
[code:205b0]
beryl: water: GL_ARB_fragment_program is missing
[/code:205b0]

However, glxinfo does report that this extension is there:

As you can see, it is listed in the OpenGL extension section. I am also pretty sure that my ATI Radeon 9600 Pro graphic chip (RV350) does have a pixel shader.

Any ideas what's the problem here? Could it be that even though glxinfo lists GL_ARB_fragment_program as OpenGL extension, it is not supported by the driver or something? I am using the open source radeon module which comes with the kernel 2.6.19, along with an AIGLX server.

Maybe this is helpful:

I'd be grateful for any hints :-)

This was a bug with either the X server or beryl that shows up when using beryl with Xorg versions prior to 7.2. It is fixed if you use Xorg 7.2 however.

Thanks a lot. Updating to X.Org 7.2 did solve the problem (I was using X.Org 7.1 before). I can now admire the nice watery effects on my desktop ;)

However, with the new X.Org version a new problem came up with Beryl: resizing windows doesn't work properly any more. More precisely, when I hover over the lower right corner of a window, I see the mouse pointer changing to a resize-image-looking pointer-icon. When I click the left mouse button (and hold it) and move the mouse somewhere to resize the window, whilst the pointer changes its location, the window stays the same. Only 1 or 2 seconds later do I see the window changing size, as one would expect. So, in fact, it's not like resizing isn't working; it's just working at a snail's pace ;) This is somewhat annoying, because it makes it kind of hard to really assess how the resized window will look like (and if it's how I want it) if the resizing doesn't work as fast as I move the mouse.

Otherwise, everything seems to work alright. Moving windows isn't a problem, it works as fast as it should, even with wobbly windows enabled. It's really just the resizing. It also doesn't matter whether I use clicking on the corner of the window or the Alt+F8 shortcut. It's slow as molasses :(

Note that I am not absolutely sure if this is caused by X.Org 7.2 itself. Updating X.Org did involve updating a bunch of other things, too, e.g. Mesa 6.5.1 to Mesa 6.5.2. At the moment I'm not really sure where to start looking for the error. Is this a known problem? Any ideas on how to fix it, or even just how to find out what causes it? Thanks again... :)
