Is this possibly related to OOP-R on Adreno GPUs with older versions of Android?

To the original bug submitter: can you include the contents of chrome://gpu? Can you test if going to chrome://flags/#enable-oop-rasterization and setting "Out of process rasterization" to disabled fixes the bug? This is a Lollipop Adreno device, and so ideally should be disabled in 69.0.3497.84 as per https://storage.googleapis.com/chromium-find-releases-static/a25.html#a25f8deadd557351da33764f9818c55d278c61e8

I am also affected by this - text rendering on my device very similar to posted screenshot. Tried setting out of process rasterization to disabled, problem remains. Running Qualcomm Adreno 430 on a Nexus 6P with Chrome 69.0.3497.100.

Thanks for all the gpu info. It's really appreciated to help try to track this down. Can repro on a Nexus 6P with Marshmallow on ToT (r592479) on something Wikipedia: https://en.wikipedia.org/wiki/The_New_York_Times. Refreshing the page yields a broken first paragraph (although repainting may or may not fix this). However, this only is broken for gpu rasterization and not oop rasterization, so far as I can tell. The above users have oop rasterization disabled in their gpu info, so it's definitely off. Additionally, disabling gpu rasterization entirely and using software rasterization also fixes this. It's very curious. I'm going to try to bisect and see if I can find where this broke.

Definitely broken at 564362. Seems to be working at 564264. It's a bit of a flaky repro, but refreshing chrome://version about ~20 times seemed most reliable. I tested 564264 quite a bit to make sure it was good and I'm reasonably confident. https://chromium.googlesource.com/chromium/src/+log/3eae45e380e99ac996aa4fc2286c3b16fe75c0fb..3860f3e4d199e934052b3486a226dde44fb22e9a?pretty=fuller&n=10000 Nothing jumps out at me here. Maybe time to dig in and build directly.

Sorry, ccameron, this is your change: https://chromium.googlesource.com/chromium/src/+/fc70961580f6f6bd2498fd3242cb6ab35362cefc If I set prefer_use_gl_clear = false, then everything works ok.

Hello, I filed https://bugs.chromium.org/p/chromium/issues/detail?id=888345 that's been merged into this one. Do you think this fix is going to help with 888345 as well (where the "messed up" visuals look somewhat different)?

Nov 22
This change is *NOT* merged into M70.. It was merged into branch 3558 which was a daily M71 branch that hasn't gone anywhere.. The target was M70 which was 3538; although I think it is too late to merge. Issue 907559 was opened because it was still on M70.

I don't know how many users are affected (my partner is, so I'm biased) but this unfortunate mistake during the merge process IMO deserves a postmortem.
,
Dec 5
Would the comment in #27 not have been generated if I'd merged to the correct branch? (I assumed it was there because I hadn't put the merge-merged-3558 label). I know that when one merges something to a release branch without approval, a warning is generated -- perhaps we should have some similar warning for merging into any branch? In that case, my merge in #22 would have triggered a warning. |
