BriskBard, CEF4Delphi, WebView4Delphi, WebUI4Delphi and WebUI4CSharp

I have some pages where TCEFBrowserThread.WebpagePostProcessing is firing multiple times, for instance https://www.delphitools.info/

I suspect this is because the isLoading from cef_load_handler_on_loading_state_change is fired once per loading iframe, and it's likely webpages with dynamically refreshed portions could triggered the loading state changes "forever".

I have worked around it by using a timer to trigger the snapshot rather than a sleep, the first WebpagePostProcessing call triggers the timer, and the timer then triggers the snapshot only once (cf. https://github.com/EricGrange/cefHtmlSn ... a9f0822737)

Is there a way to force a full repaint by Chromium ?

I am seeing some incorrect painting in areas where an animation occurs, see below the artefacts on the background. This is where the cookie law banner stands before being deleted, and it disappears with an animation.

If a full repaint is possible, then it may result in a cleaner render for the purpose of snapshots, where incremental paints are not required (and the incremental paint updates before the full repaint could just be ignored)

Call TChromium.Invalidate(PET_VIEW) to repaint everything asynchronously.

Thanks, the issue is still present though the Invalidate works as expected, I will report with upstream.

I have also been filing false positive reports for each of my cef builds, according to VirusTotal, SecureAge is the only one firing on basically any Delphi + CEF4Delphi build, I do not know if they have processed my report.

Hopefully if enough Delphi devs report false positive, this problem will be history!

I tried loading https://delphitools.info/ in the SimpleOSRBrowser demo and it looks ok. The WebpageSnapshot demo, which uses the same TCEFBrowserThread, also looks ok.

As far as I know, virustotal only shows the information given by the different antivirus programs. You should send a message to the company that created each antivirus software.

I also have some false positives with BriskBard from time to time and they are usually gone the next month. Sometimes they need a message to the antivirus company and sometimes it just disappears.

With a simple snapshot at 1024x768 resolution I only have an issue on the edges, the issue at the top happens when running the script at https://github.com/EricGrange/cefHtmlSn ... -buster.js which removed the cookie banner, which results in a slight scrolling of the page.

Yes, that is what I've been doing. I am feeding them the intermediate builds with false positives as well.
