Hi psychon@znc.in

i see you change the bug from new to needinfo but you did not leave any comments, could you leave a comment and then change again to needinfo please ?

Well... Assuming I wanted to investigate this crash, what would you want me to do? Whatever kms_pipe_crc_basic is (is it part of Intel GPU Tools? What is Intel GPU Tools anyway?), it's not part of cairo. The Google approach did not work either: https://github.com/mkuoppal/intel-gpu-tools/search?utf8=%E2%9C%93&q=kms_pipe_crc_basic&type=

So basically, I cannot say more than "sorry, what?" on this bug report and I do not even know which cairo backend is used, or anything.
