You are right that this is not the primary cause for the hanging. I found out that the freeze issue that is affecting me is - <a href="https://www.reddit.com/r/thinkpad/comments/4ajgjh/t460_suspend_problem_with_linux/">https://www.reddit.com/r/thinkpad/comments/4ajgjh/t460_suspend_problem_with_linux/</a> BTW, I noticed that the following when the backtrace as discussed in this bug occurs on my laptop: When I switch virtual desktops the image of the window in the previous desktop is shown for some time if the current desktop does not have any windows. This happened consistently with plasma desktop of KDE 5, I have not checked others.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
