I would like to report a problem regarding the EO.WebBrowser for .NET.

We use it from ArchiCAD and the browser crashes randomly inside it.

Sometimes it just stops working, the whole webpage inside it stops working. After reopen the browser plugin shows only a white screen.
Sometimes after several minutes it also stops working without any reason. It is working properly and suddenly crashes.
There are cases when I leave the computer and when I get back I see it has crashed. Nothing was running in the back, I've done nothing, just left the computer.

We debugged our web application, and in the cases of these crashes it continues to work, we just can not reach it through the browser plugin.
The crashes are totally free from our app's behavior.

See the video (1:17): VIDEO

Please, suggest or provide some solution for this problem, in this current situation we can't use the plugin.

Thank You in advance!

This problem is still existing on newest Version of EO. (16.2.44)!
We are using EO browser in a kiosk environment that runs 24hours a day. Sometimes we leave the computer and
when we come back, browser engine has crashed and shows a white screen.

If we restart the engine, nothing gets rendered. After we restart the PC, browser comes back.

Today I installed the browser on a different computer (Intel Compute Stick) and it shows the white screen from the beginning.
There's no way to make it render the page (content is loaded and present in the DOM - JS is executed too).

What I found out so far:
If I set the option "DisableGPU" to false, everything gets rendered fine until I turn the option back on, then the engine crashes immediately.

We upgrade from 16.1.75.0 to the latest version of EO.WebBrowser and some of our customers are reporting to us the same "white screen" problem...

This problem seems to affect only computers on Windows 7, we don't have any error or something else : all the opened webbrowsers (same engine) just disappears and show a white screen instead.

The EnableLargeAddressspace is already set to true.

We actually use the 16.2.37, we will try with the 16.2.44 and see... but the changelog does not leave much hope.

We've upgraded to 16.2.44 and problem still the same.

Application Id is 211_A26_AUSS.

We've downgraded to 16.1.75.0 until this issue is resolved

Thanks!

We do not see any crash report on our end. Can you try to set this property to true and see if it helps:

Thanks!

Hi guys,
today I found another reason, why or WHEN the white screen appears (randomly).

I was writing a proxy that stands between browser and webserver in order to serve content even when browser's offline.
What I noticed is, that if there's a "Content-Length" in the HTTP header, browser randomly closes the reading stream for this ressource too early, what means, that some data can't be send properly and then the white screen appears and engine crashes.

If I remove the "Content-Length" (it's legit not using it, because not mandatory) the problem disappears and I never see the white screen again. If I send the content length again, browser crashes again - it is 100% reproducible and happens mainly on larger files (> 800 kb).

This might help you...

In my option this is not a proper solution, because almost every site requires gpu support to be rendered smooth.
CSS animations without gpu acceleration look pretty bad....

Usually this occurs when there is a problem with the display card driver. In that case it is not possible for us to "fix" that problem. The only viable option is to avoid it by disabling the GPU.

Thanks!

We do not know why 16.1.75 works but 16.2.37 doesn't work. We do have many cases where the GPU has caused the crash. If you can give us remote access to the machine of that has the problem, we will be more than happy to investigate further.
