OSR: Transparent background broken since version 83

magreenblatt commented 4 years ago

Original report by vsergeenko (Bitbucket: vsergeenko, GitHub: vsergeenko).

Since version 83, background_color can no longer be used for transparent background.

Easiest way to reproduce problem:

Run cefclient with a transparent render and test page.

cefclient --off-screen-rendering-enabled --transparent-painting-enabled --url=data:text/html;base64,PGh0bWw%2BPGJvZHk%2BPGgzIHN0eWxlPSJiYWNrZ3JvdW5kOiAjZmZmOyBjb2xvcjogIzAwMDsiPk9wYXF1ZSB0ZXh0PC9oMz48L2h0bWw%2B
After loading the page, you will see a transparent page (displayed as black) with text on a white background (version 81) or a completely white background (version 83).

I look at changes between branches 4044 and 4103, and I see a new patch renderer_host_1070713 in fa519f5108661885761a408133d97a3452a5a36e. It is probably related to the problem, but I cannot confirm this.

Build on which problem is reproduced:

define CEF_VERSION "83.3.7+g42fc10a+chromium-83.0.4103.14"

#define CEF_VERSION_MAJOR 83
#define CEF_VERSION_MINOR 3
#define CEF_VERSION_PATCH 7
#define CEF_COMMIT_NUMBER 2194
#define CEF_COMMIT_HASH "42fc10a6cdd029f8a0f2e8fc0a9249cfd627d99e"

Does not reproduce:

define CEF_VERSION "81.3.10+gb223419+chromium-81.0.4044.138"

#define CEF_VERSION_MAJOR 81
#define CEF_VERSION_MINOR 3
#define CEF_VERSION_PATCH 10
#define CEF_COMMIT_NUMBER 2188
#define CEF_COMMIT_HASH "b223419041d549e565c1c53e5ff7a17436f681fb"

Tested on Windows 10 x64.

i think it’s related to this code (which was removed removed at 82 or 83):

https://bitbucket.org/chromiumembedded/cef/src/71768ea6c32deba08d16c2c77bc9ddce5f33387b/libcef/browser/osr/web_contents_view_osr.cc?at=master#lines-126

void CefWebContentsViewOSR::RenderViewCreated(content::RenderViewHost* host) {
  if (!host)
    return;
  CefRenderWidgetHostViewOSR* view =
      static_cast<CefRenderWidgetHostViewOSR*>(host->GetWidget()->GetView());
  if (view)
    view->InstallTransparency();
}

Yeah, this seems to fix (I’m not sure if it’s a right fix though…):

@{557058:2f2a2aee-b500-4023-9734-037e9897c3ab} are there any plans to go forward with this issue? Its impact was significant enough for us to downgrade CEF in our project, we (and i suppose others) are missing out on important Chromium (security) fixes. We would very much prefer an official fix rather than cherrypicking the above commit, which hasn’t been confirmed, or hacking in our own fix without experience with Chromium.

magreenblatt commented 4 years ago

Note that the timing of InstallTransparency (which calls SetBackgroundColor) is somewhat sensitive. See issue #2482 and https://crbug.com/1070713 for background.

magreenblatt commented 4 years ago

Contributions to fix this issue on all platforms would be welcome.

magreenblatt commented 4 years ago

Original comment by elad bahar (Bitbucket: eBahar).

a fix for this issue is to restore chromium code (or finding new place to add the removed function):

chromium code (moved at M82) web_contents_view.h:

class CONTENT_EXPORT WebContentsView {
...
virtual void RenderViewCreated(RenderViewHost* host) {}
...
}

void WebContentsImpl::RenderViewCreated(RenderViewHost* render_view_host) {
  if (delegate_)
    view_->SetOverscrollControllerEnabled(CanOverscrollContent());

  NotificationService::current()->Notify(
      NOTIFICATION_WEB_CONTENTS_RENDER_VIEW_HOST_CREATED,
      Source<WebContents>(this),
      Details<RenderViewHost>(render_view_host));

  // restore this call:
  if (view_) {
    view_->RenderViewCreated(render_view_host);
  }

  for (auto& observer : observers_)
    observer.RenderViewCreated(render_view_host);
  if (delegate_)
    RenderFrameDevToolsAgentHost::WebContentsCreated(this);
}

Fix this, fast.

ARCHIE his project is blocked, and my project is blocked. CEF is old….

magreenblatt commented 4 years ago

Original comment by Florian Simon (Bitbucket: Florian Simon).

My project is also blocked, but please remember that the CEF maintainers do not owe you anything. Yes, CEF is not new, but it’s still getting maintained regularly. If you’re in dire need for a fix, why not contribute? There’s already a PR if you need inspiration.

Testing M84 and M85 with a Debug x86 build on Windows 10:

cefclient.exe --off-screen-rendering-enabled --transparent-painting-enabled --url=http://tests/transparency

The following issues remain:

There’s an approximately 5 second delay between when the page initially loads (showing a white background) and when the transparency is installed (rendering switches to the expected rainbow background). It seems that CefWebContentsViewOSR::RenderViewReady and InstallTransparency are called early as expected, but for some reason the Compositor does not apply the transparency immediately. This does not reproduce with --enable-gpu, or with new browsers created via Tests > New Window or Tests > Popup Window (even if those new browsers are created immediately without waiting 5 seconds).
Tests > Popup Window loads google.com in a new browser window. With GPU disabled this browser will have a white background. With --enable-gpu this browser will have a transparent background. The tag does have white background specified, so the behavior with GPU disabled is the correct/expected behavior.

CEF will never be un-broken, it will be unusable forever, if this goes on.

You can see Marshall has made progress in a fix. Maybe if you contributed it would get fixed more quickly?

David, please stop posting unproductive comments. If you want this issue fixed faster then I suggest you contribute as others have suggested.

Marking this issue as Resolved. The remaining problem with GPU enabled (from here) is likely a Chromium issue and not something that we will fix for CEF specifically.

We have a similar white screen issue occuring on Windows 7. Do you think it’s related?

Are you using a build that contains the above fixes? Does the problem only reproduce with OSR and transparency enabled?

‌

magreenblatt commented 4 years ago

Original comment by Florian Simon (Bitbucket: Florian Simon).

I tried using this build: http://opensource.spotify.com/cefbuilds/cef_binary_85.2.11%2Bg0202816%2Bchromium-85.0.4183.83_windows64_minimal.tar.bz2

It happens with OSR, yes. Regarding the transparency, only the areas that are supposed to be transparent are all white.

magreenblatt commented 4 years ago

Can you provide an HTML example or URL that reproduces the problem? Does the problem reproduce with cefclient? Does it only reproduce for you on Windows 7? Have you tried multiple Windows 7 machines with different GPU hardware?

magreenblatt commented 4 years ago

Original comment by Florian Simon (Bitbucket: Florian Simon).

Is there a website that you know used to be broken before the fixes? I’m not using the Windows 7 machine myself, our QA team is. I can ask them to try cefclient on a sample page if you know one.

As far as I know, we’ve performed tests on a RDP machine (which doesn’t work, but I know why), and a single machine with up-to-date graphics driver.

Unfortunately, I can’t show our proprietary application. But I guess our QA team can help :slight_smile:

magreenblatt commented 4 years ago

Is there a website that you know used to be broken before the fixes?

The example here was broken before the fixes. You won’t be able to test using RDP for the reasons that have been reported in issue #2947 and issue #2963.

Sorry, I missed it. I’ll ask our testers to try this. Thanks!

Hi! Do we actually need the transparent painting flag? In our app too? I don’t remember ever using it.

On another note, our testers are currently testing the program in Windows 7.

Florian your Windows 7 problem sounds like issue #2963. Let’s keep this issue can focused on transparent painting specifically.

Original comment by Florian Simon (Bitbucket: Florian Simon).

Sorry, that’s correct. I will ask my tester to check whether this is fixed or not with Mesa3D, then copy the DxDiag file to the other ticket.

Original comment by John Moore (Bitbucket: rljohn, GitHub: rljohn).

I’ve tested this fix on:
CEF 85.3.9+gb045a6e+chromium-85.0.4183.102 / Chromium 85.0.4183.102

If “--disable-gpu-compositing” is enabled - on x64, transparency works as expected, but on the x86 build it does not.
