------- Comment #26 from [EMAIL PROTECTED] 2007-04-10 02:03 PST -------
The following patch fixed SecondLife for me by giving
up after a few retries.
The client uploads this 1024x1024 texture several times
per second (but not every frame, I think). So to get
a decent frame rate I actually lowered the retry count
to 1 and removed the usleep() in my copy of mesa.
Despite missing such a big texture, the game looks fine
except for a tiny line of garbled pixels over the button
bar.
Of course this isn't a suggested fix. Maybe the retry thing
should go in for robustness, but the real bug is obviously
somewhere else.
