i have a web browser on a win form in dot net (4.6.2).
it's visible = false when the page loads. we ask the end user some questions and then build a URL from their responses.
that url is sent to the browser and it's made visible.
I have a couple computers here and there that won't show the rendered web page to the end user. It's there in the browser though.
i can right click and view page source and it's what it should be. I can also use my mouse and move around the browser and the cursor will change when it moves over stuff on the page just like it was really there but the entire web browser control is white with nothing else.
How can i fix this?
So far it's happened on a win 8.1 machine and a 2012 r2 server. i have about 5 win 10 machines it works fine on so far.
i found a suggestion on another post where they were getting a pure black screen. i tried their fix of turning gpu rendering off but it didn't fix the issue.
Thanks!

Hi,
Usually this does have to do with GPU. You can verify whether you have indeed turned off GPU by looking for all rundll32.exe process in your task manager and check the command line arguments of these processes. If you see one with "--type=gpu" command line argument, then it means the GPU is not turned off properly. In that case make sure you turned off GPU BEFORE you start your main form. For example, a good place would be Program.Main method.
If GPU has indeed been turned off, you can try to use our TabbedBrowser sample application to load the same page and see if it displays correctly. We can then go from there.
Thanks!
