If this is using a PDF viewer extension then it isn't the internal PDF viewer.

This sounds like a (lack of) GPU rendering issue?

The process they are going through is disabling gpu compositing. Running chrome with --disable-gpu should reproduce the same behaviour. #0 can you confirm you can reproduce without the gpu crashing by using that flag? Also what extension are you using? Some changes with pepper and mac went in and got reverted a few times in the last week. Can you still reproduce this on the latest Canary? Thanks.

The video shows the "preparing document for printing" dialog changing size back and forth, which seems like a different bug from the original. Can you open a new bug and assign to pdf team? Thanks. |
