Note : I am marking the bug as stable blocker for now.

tagging Android since this is Blink regression.

Remove M-59 stable release blocker because impact is too low to block the current roll-out and the fix is likely to be more risky than we would merge.

But leaving it as an M-60 stable blocker because extensions use brightness filters for various purposes and we don't want to leave such cases broken.

Just to update the latest behaviour,
Able to reproduce the issue on Mac 10.12.5 using latest canary #61.0.3130.0.

wangxianzhu@ - Gentle Ping...!!
Could you please have a look into the issue as it has been marked as a stable blocker.

Thanks...!!

I will fix this before M60 stable release.

Fix background painting of row as layer with paint offset

The dirtied-columns calculation was incorrect in the case (due to
incorrect coordinates of the cull rect), causing the row background
is not painted behind some cells.

Remove the dirtied-columns logic. Now it's the same as what we did
before https://codereview.chromium.org/2786463004.

Justification of removing the logic about performance:
- Self-painting rows are rare;
- In a large table containing many self-painting rows, we won't paint
  the rows out of the interest rect.
- We didn't have performance issues reported when we didn't have the
  logic;

Verified the issue on windows 10, Mac 10.12.5 and Ubuntu 14.04 using latest chrome  version #61.0.3138.0 as per comment #0.

Observed that background color of the cells did not get cleared. Hence, the fix is working as expected.
Attaching screen shot for reference.
Hence, adding the verified labels.

Thanks...!!
