Hello Harish, could you please try to get a dmesg log with debug information, drm.debug=0x1e log_bug_len=2M(or bigger) on grub? Also a screenshot of the corruption would help. Have you tried disabling/enabling HW/SW acceleration? This problem happens since the beginning of the session or takes some time? A bisection could definitely help in this case. Thank you. Thank you for the response. Please take note of the following: 1.) This problem happens from beginning of the gnome session. 2.) How do I disable/enable HW acceleration? 3.) I can confirm that the problem is somewhere in the 4.12 kernel. As mentioned, somewhere between 4.12 rc1 and 4.12.1 to be exact. I do not have any experience in bisecting unfortunately and I cannot dedicate much resources to the bisecting process. 4.) I cannot take a screenshot of the corruption as its the gnome animation that is the culprit. I can take a video of the problem and email it, if that could help. 5.) I will provide the dmesg log in the near future. Thanks in advance! here is the bug report for a potential gnome bug regarding the animations. https://bugzilla.gnome.org/show_bug.cgi?id=788867 However, right now I'm not sure if this is a gnome issue or a kernel issue. Using the 4.9 LTS kernel definitely solves this problem. The possibilities are: 1.) Is gnome not playing well with the new graphics stack? 2.) IS there a regression in the kernel? I hope the developers from both projects can interact with each other to get to the bottom of this. First of all. Sorry about spam. This is mass update for our bugs. Sorry if you feel this annoying but with this trying to understand if bug still valid or not. If bug investigation still in progress, please ignore this and I apologize! If you think this is not anymore valid, please comment to the bug that can be closed. If you haven't tested with our latest pre-upstream tree(drm-tip), can you do that also to see if issue is valid there still and if you cannot see issue there, please comment to the bug. Closing, please re-open if still occurs. |
