I need more information:
- Did you upgrade anything else at the same time, such as Mesa?
- Did you try the dithering workaround mentioned in bug 74700?
- Attach the screenshots that you emailed me to this bug.

If changing the kernel affected the bug, then it is not the same issue as bug #74700.  That's why Matt asked you to report a new bug. :)

Yes, please upload a screen shot of the issue.  Without that, we won't have any idea what the problem is.

Thanks.

Required information still missing after ~2 years.

Among other changes, DOTA2 uses nowadays Source engine v2 instead of source engine v1 (against which this was reported).

-> Closing this as obsolete / WORKSFORME.  If there's a problem with a DOTA2 version that is currently available, please file a separate bug.
