Public bug reported:
Binary package hint: beryl-core
Package is either beryl-core or beryl-manager
Beryl:
If I open multiple windows of any application under any user on any desktop or
multiple at once, they open black. This is dependent on many things, I guess
you could say, it literally depends on the "area" used by the cumulative total
of windows I have open. The more open, the more likely I am to have the issue
and it is very reproducible. When a window shows up black, I can reduce the
area of the window horizontally, vertically, or both to eliminate the problem.
The more windows I have open, the smaller I have to make subsequent windows.
It seems to be independent of having windows on multiple desktops or having
transparency effects and so on applied. I have found a workaround for the
issue, seems to be 100% so far: under Advanced Beryl Options in the right-click
menu of the Beryl Manager icon in the Ubuntu gnome "systray", if I select
"Copy" as the "Rendering Path" the issue is eliminated, however "wobble" and
the snaky-minimize action have lower performance, I assume "Texture from
Pixmap" is supposed to be higher performance. I have yet to be able to
re-create the issue while using Copy instead of Pixmap. I know I'm not the
only one to have this issue, I hope this helps as a workaround and for finding
the root cause!
Other technical notes:
- I am using x86 under an AMD64 for compatibility reasons
- beryl-manager is being loaded from within my user profile under the gnome
window manager as a regular startup item to initiate the software
- I am NEW to Ubuntu on x86 coming from using Debian under SUN4U Arch., please
forgive some possible technical oops on my end related to *nix, I'm used to
nothing working and being given "lol" as the net reply :)
- I am using the nVidia driver automatically downloaded by Ubuntu on 22APR07,
my Ub distribution was downloaded on 20APR07 from standard-support release
repositories 7.04
- AMD 64 Venice-Core 3000+, 1GB PC3200, nForce4, GeForce 6600GT PCIX 128MB
- I receive no error messages, just the black windows I can resize or change
my settings to resolve
