Hi I am using Chimera alpha 1.4 build 27395 in Ubuntu 9.04 Jaunty 32 bits version, in a laptop with Core2Duo@2.4GHz each core, 4 Gb RAM. When I use Save Image, sometimes if I increase the size of the image or increase supersmple values, Chimera will crash with this terminal message: X Error of failed request: GLXBadPbuffer Major opcode of failed request: 128 (GLX) Minor opcode of failed request: 28 (X_GLXDestroyPbuffer) Serial number of failed request: 107906 Current serial number in output stream: 107908 (The last 2 numbers will vary between crashes) After restarting Chimera sometimes I can save the image using the same image specifications, other times it will keep crashing and only reducing the size or the Supersample numbers, I can save the image. Is this laptop not powerful enough? Do you need more information? Should I try another build? Thank you in advance Victor Alves PS: My first message to the BB, so congratulations to the developers for an excellent piece of software.
