At least, I did not notice it for some time now. What is very strange, Chromium does not redraw. I can click on buttons and they seem work (e.g. close tab quits the application), however, the browser does not show any changes. Please, can you specify the term "latest kernel" next time? Do you mean a certain latest release or the current master? I do not build my own kernels...</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
