--- Comment #12 from Marek Ol??k <maraeo at gmail.com> --- All writes to valid_buffer_range are protected by a mutex. Only the reads are not. I've got no idea what to do with invalidate_buffer. If we added mutexes everywhere, it would slow down the driver. I think that calling BufferData in one thread and using the buffer for rendering in some other thread is a race condition in the application and should be fixed in the app. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
