Andrea, these errors are important for us to understand why they occurred to make sure everything is working as it is supposed to. OpenGL 4.3 is substantially different from 1.x. In the last release I have the following errors (on terminal) at startup:
BC_Signals::x_error_handler: error_code=8 opcode=154,31 id=0x111 BadMatch (invalid parameter attributes) BC_Signals::x_error_handler: error_code=172 opcode=154,26 id=0x3400002 GLXBadDrawable BC_Signals::x_error_handler: error_code=182 opcode=154,32 id=0x3400002 GLXBadWindow
GG booted Arch here which is mostly up to date, and did not see these
errors BUT I think that you have an Nvidia graphics card. Is that correct? Also, did I understand correctly that you got these errors immediately on startup before you did any work? If not, then what operations did you perform that caused the error. Thanks again for testing - we appreciate it.
