Note: this bug has been posted to the Gentoo bugzilla bug tracking system, but I realized it would be more appropriately addressed here. (Because no one other than nvidia has access to the source code...)
Anyway, here's the details:
xclock does not load - instead, an error message is printed to the console. (I am using xclock as a demonstration example. A similar bug also happens when I try to run nvidia-settings). Also, transparency seems to be messed up in fluxbox, but I'm just going to stick to the xclock bug for this because I think
it's a good representative example.
Steps to Reproduce:
xclock did not load.
This error was printed to the console:
X Error of failed request: RenderBadPicture (invalid Picture parameter)
Major opcode of failed request: 155 (RENDER)
Minor opcode of failed request: 10 (RenderTrapezoids)
Picture id in failed request: 0x0
Serial number of failed request: 58
Current serial number in output stream: 120
xclock should have run with no problems.
I have sent an email to firstname.lastname@example.org
with the appropriate nvidia-bug-report.log
If anyone else has encountered this, and has a solution / workaround, please let me know.
