(You don't physically notice in `OffScreen`, the errors are in the `debug.log` file).\r\n\r\nI have raised the issue on http://magpcss.org/ceforum/viewtopic.php?f=6&t=13997\r\n\r\nSimply workaround is to use the `--disable-gpu` command line flag (search the source if you require an example of it's usage).\r\n\r\nIf you experience this problem, please simply post your Windows Version and graphics card make and model.\r\n\r\nWhen I have more information I will post it here. No need to create an issue.\r\n\r\nLog entry is:\r\n```\r\n[0318/115339:ERROR:gles2_cmd_decoder.cc(12228)] Context lost because SwapBuffers failed.\r\n[0318/115339:ERROR:gles2_cmd_decoder.cc(4471)] Error: 5 for Command kPostSubBufferCHROMIUM\r\n[0318/115339:ERROR:gpu_command_buffer_stub.cc(1224)] Exiting GPU process because some drivers cannot recover from problems.\r\n[0318/115340:ERROR:gpu_process_transport_factory.cc(652)] Lost UI shared context.\r\n```\r\n\r\n#### Update\r\n- For those using `49.0.x` you must disable `GPU` acceleration (example below)\r\n- For those using `51.0.x` see comments about `app.manifest` below, if that doesn't work then disable `GPU` acceleration.\r\n\r\n If your seeing Flickering/Flashing/Dissapearing/Redraw on page rendering, that's related to this issue.\r\n\r\nFor those requiring an example of using the `disable-gpu` command line argument see https://github.com/cefsharp/CefSharp/blob/1e18b55116190ea4e1b0c84dc7e6a2b84ec25eb2/CefSharp.Example/CefExample.cs#L77"},"comment":{"url":"https://api.github.com/repos/cefsharp/CefSharp/issues/comments/226992078","html_url":"https://github.com/cefsharp/CefSharp/issues/1634#issuecomment-226992078","issue_url":"https://api.github.com/repos/cefsharp/CefSharp/issues/1634","id":226992078,"user":{"login":"tylerlong","id":733544,"avatar_url":"https://avatars.githubusercontent.com/u/733544?v=3","gravatar_id":"","url":"https://api.github.com/users/tylerlong","html_url":"https://github.com/tylerlong","followers_url":"https://api.github.com/users/tylerlong/followers","following_url":"https://api.github.com/users/tylerlong/following{/other_user}","gists_url":"https://api.github.com/users/tylerlong/gists{/gist_id}","starred_url":"https://api.github.com/users/tylerlong/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/tylerlong/subscriptions","organizations_url":"https://api.github.com/users/tylerlong/orgs","repos_url":"https://api.github.com/users/tylerlong/repos","events_url":"https://api.github.com/users/tylerlong/events{/privacy}","received_events_url":"https://api.github.com/users/tylerlong/received_events","type":"User","site_admin":false},"created_at":"2016-06-19T11:22:30Z","updated_at":"2016-06-19T11:22:30Z","body":"@amaitland Thank you for the reminder.
