Beryl Black Window Bug

[amistry]

Since I haven't seen a post on this in the FreeBSD forum yet I'd just like to confirm that the black window bug also appears in FreeBSD using beryl. I'm using a Geforce2 Go. Besides that performance is pretty good. I've read through the threads on the Linux forums and the suggestions for the work-arounds work, but the performance hit is significant on this older machine. Is there an ETA on when this bug will be fixed? What is the current progress? And lastly is there any missing functionality in FreeBSD that is hindering the bugfix (eg. AMD64)?

Thanks,

The 'black window bug' is a limitation of the NVIDIA UNIX graphics drivers' GLX_ext_texture_from_pixmap implementation, which doesn't currently handle certain out-of-video-memory cases well. There are plans to address these problems, but I can't give you an ETA. With respect to a FreeBSD/amd64 port, certain kernel functionality is still missing at this point. Please see the related threads on this forum for details.
