Steps to reproduce the crash on my laptop: 1) Install <a href="https://github.com/krypt-n/bar">https://github.com/krypt-n/bar</a> which gives you the lemonbar executable 2) ./crash_me.sh | lemonbar -f "Droid Sans" The script pipes lines into lemonbar which then should be shown on the bar. Further observations: 1) the GPU hang occurs after the first update of lemonbar. In the script this is after 1 second (sleep 1). If this is changed to e.g. sleep 30 the crash occurs after 30 seconds. 2) The crash occurs for some XFT fonts, but not for all. I suspect that the crash orginates from XFT font rendering. 3) Changing the echod text to something different results in no further crash. So oddly, this seems to be a rather fine tuned issue. 4) The crash occurs independently of the chosen X window manager. If I can help further, I will try to do so.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
