[19:53] <furkan> tjaalton: so i figured out how to reproduce that checkerboarding bug... it happens after suspend/resume, and i found yet another symptom of it
[19:55] <furkan> tjaalton: https://www.dropbox.com/s/7hj8qi3w3qc35jb/IMG_20150405_155434.jpg?dl=0
[19:56] <furkan> both that and the checkerboarding in the global menu happen _only_ after a suspend/resume cycle
[19:56] <furkan> and the checkerboarding only happens at the top area of the screen
[19:57] <furkan> so if you recall that video i shared some time ago... https://www.dropbox.com/s/ez2v03oetppecgx/VID_20150324_020612.mp4?dl=0
[19:57] <furkan> the checkerboarding only happens for the first few menu entries
[19:58] <furkan> and similarly, if i launch say a new full-screen firefox window, there is checkerboarding along the top of the screen as the window appears
[19:58] <furkan> i guess at this point i've got enough info to submit a bug report, so i'll do it
[20:49] <furkan> here's the report: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1440602
[20:49] <furkan> tjaalton: wanna +1 it if you can reproduce with your PC also?
[21:10] <furkan> and also submitted a second bug... this one's even worse as it results in the system being unusable: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1440606
