Assigned to johnylin@, who kindly look into this problem.

Thanks!

Also reproducible on Elm 11562.0.0

johny is far from their machine now. As it takes more time to flush device, I will take over this issue.

This is caused by chrome uprev, 73.0.3666.0 -> 73.0.3667.0.
https://chromium.googlesource.com/chromium/src/+log/73.0.3666.0..73.0.3667.0?n=10000

I find this is caused by https://chromium-review.googlesource.com/c/chromium/src/+/1368832.

+jdarpinian@, +kbr@, may I please ask you to fix this issue ASAP?

I would like to investigate but I do not have an elm or hana device. Are other devices affected? Do you have a suggestion for how I could obtain an affected device for debugging?

I think this issue is reproducible only on MTK8173 devices. There are few MTK8173 devices besides hana and elm.

+textor

Andrew, can you help assign an elm or hana to jdarpinian ? I'm not sure who on your team is responsible for allocations for those two older models.

marcheu@, hoegsberg@, dcastagna@: could we borrow one of these devices on which to reproduce this problem?

What is the update of this?

jdarpinian@ talked with the ChromeOS team and we should have a loaner device today on which to reproduce the problem.

I have a fix that I believe will work. I can't test it this week because I am out of the office, but I will submit it anyway and verify next week when I get back. http://crrev.com/c/1425728

gpu: Fix format/internalformat confusion

Several code paths in the command decoder were creating textures with
format == internalformat. However, many internalformat values are not
valid as format values. This was not checked before
http://crrev.com/c/1368832 , but now it results in errors. This change
calls TextureManager::ExtractFormatFromStorageFormat to get the correct
format for the specified internalformat.

Fixes video display in the YouTube Android app on some Chrome OS
devices.

Should be fixed. Please reopen if not.

I verified this CL fixes the issue.

Thanks.
