Yeah, it is the same, but, it might be that it is not a bug with mesa at all(?). Long story short, after investigating further, it turns out that DRI3 works quite well with compiz, marco and in lxde, lxqt. The actual problem happens only when mutter is window manager (still, it doesn't explain why it works well with DRI2), I've tried MATE DE with different WM and as expected, all others work well except mutter. Hope this new info helps, and if it turns out it is mutter bug and not DRI3 (doesn't make sense), I apologize for wasting your time (should have done this earlier...), and we can close/delete this bug report. It still doesn't make any sense why it would work well with DRI2 but not DRI3 on mutter.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
