Windowed NPAPI plugins aren't showing if opened in a background tap until the browser resizes

Reported by, Jan 18 2014 Back to list

Issue description

UserAgent: Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/32.0.1700.76 Safari/537.36

Example URL:

Steps to reproduce the problem:
1. Google ""
2. ctrl+click the first result to open it in a new tab
3. Switch to the new tab, Silverlight element does not show up, untill the browser is resized

(the same problem occurs for all silverlight controls)

What is the expected behavior?
The Silverlight content should show immediately when switching to the new tab

What went wrong?
Silverlight content in new tabs is not being shown

Does it occur on multiple sites: Yes

Is it a problem with a plugin? Yes Silverlight

Did this work before? Yes I'm fairly certain this used to work within the last couple of weeks

Does this work in other browsers? Yes 

Chrome version: 32.0.1700.76  Channel: stable

I am able to reproduce this issue on Latest Stable#32.0.1700.76 & Latest Beta#33.0.1750.46. This issue got regressed in M32.

PS: Working fine on Latest Canary#34.0.1803.2 (Official Build 246787).

Below is the narrow bisect window:
You are probably looking for a change made after 234675 (known good), but no lat

Thank you.

As suggested in 335656, it only affects Silverlight controls that open in windowed mode (which is about 99% of Silverlight applications). is affected by this too. If you open a panorama in a new tab you won't see anything until you resize the browser window.
This affects Netflix as well. When clicking a link or right-clicking to open a Netflix url in a new tab, the entire Silverlight component/video is invisible until the window is resized.

Any site opened by seems to have this issue. Version 32.0.1700.102 didn't fix this issue today.

I'm setting merge-requested for M33. Karen: I'd be surprised if we merge this to M32?
Hello Jam,

I see the issue has been fixed, that's great.
When can we expect to see the solution in the latest Chrome version ?

Approved for M33.
When will M33 be released.  Can I get a beta version?
