Some compositor issues

So, now that the compositor is in trunk and everyone is excited, this might be a good time to mention some “issues”. Firstly, it seems that there are some weird shadow redrawing problems…these just appeared recently, so it shouldn’t be hard to find the offending commit. I think I know what it is, I just […]

Trip the light fantastic

Useful uses for a compositor #1 Some videos this time, they’re not particularly good quality but that doesn’t matter. First – http://folks.o-hand.com/iain/watch-updates.ogg Its like acid, but cheaper! So what exactly are we seeing? Well, everytime a section of the screen needs to be redrawn, the compositor draws it correctly, and then picks a random colour […]

Shoot speed kill light

Some recent changes to the compositor made it feel kinda slow and laggy. Not in a noticable way but more in a subconscious something feels wrong way. I tested xfwm and it seemed fine running as a compositor, and given that Metacity’s compositor has the same heritage as xfwm’s and I’ve been checking the xfwm […]

By popular request

Some people have expressed concern about the panel drop shadows. At least three people didn’t like that they drew the shadows over the windows close to them. So in response I’ve just committed a change that makes the panel drop shadows only draw on the desktop. I think it looks quite neat and tidy actually. […]

Underground Cave Dwellers Society

A quick update on the compositor.  I updated the branch to match the trunk, so all the bug fixes have been up into the branch. Some more compositing bugs have been squashed: Changing screen resolution should work The transparency property on windows is now respected (meaning that gdk_window_set_opacity works, as does transset) Jonathan Matthew fixed […]

Ok commandos, you’ve been asking for it all week

Everyone seemed concerned about window previews in the alt-tab dialog… 20 minutes coding, 30 lines of code added, this composite lark is easy (yeah, right…). Not committed yet, a few bugs remain (note the glitches in the Gossip window corners and the terminal window doesn’t get previewed yet, and obviously the scaling), but I’m confident […]

Adventures in Compositation Land

As Thomas said, I’ve been working on hacking about with a compositor in Metacity recently. All I’ve really done is to take xcompmgr.c by Keith Packard and worked it into Metacity, so I’m not claiming that I really wrote the compositor, more massaged an already existing one into shape. The code is at http://svn.gnome.org/viewvc/metacity/branches/iains-blingtastic-bucket-o-bling/ and […]
