So far, I have been able to experimentally deduce that kernels all the way back to Linux 4.11.9 have the bug. Kernels that I've tested so far that work bug-free are linux-lts 4.9.67 and linux 4.10.9. I have yet to bisect further as the compiler is being a pain and apparently needs to be downgraded. Will update, eventually.... For note, my method of testing is opening previously said dwarf fortress game (other games not tested) and both casually and aggressively switch workspaces to and from the game window using marco, my window manager. It's guaranteed to trip the bug in under 10 minutes (usually no more than 5).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
