Looks like it was incorporating content from my other tabs in the display of that one.

wutao@ could this be a dupe or related to the other display corruption issue you were looking at?

abodenha@, can you repro this easily and does it only happen on samus?

Looks like missing/random tile issue?

We had fixed some missing/random tile issue for kernel v4.4, but users are still seeing this on other kernel (chell, v3.18): https://listnr.corp.google.com/product/208/report/72045578563
I got contacted by the user of the above report, he still saw it last week.

I was suspecting some OOM fix was the cause. But no one can verify it without easy steps to repro:

I haven't been able to repro at all. I only saw it once on my samus.
