NoState Prefetch will cache all resources except those with the no-store Cache-Control header. The “IDLE” Net Priority is the lowest possible Net Priority in Chrome.Īll resources retrieved by the NoState Prefetch are cached according to their cache headers. Subresources that are fetched will be fetched with an “IDLE” Net Priority.

Additionally, it will not fetch any resources that require user actions (e.g., auth popups, SSL client certificate, or manual overrides). NoState Prefetch only supports the GET HTTP method it will not fetch any subresources that require the use of other HTTP methods. If the main resource or any of its subresources has a registered service worker, these requests will go through the appropriate service worker. The HTMLPreloadScanner then scans this resource to discover any subresources that need to be fetched. The resource that is being loaded with NoState Prefetch is fetched.

This helps minimize the effects of something going wrong (e.g., a tab crashing) as well as prevent malicious code from accessing other tabs or other parts of the system. Each tab in Chrome, as well as each NoState Prefetch process, has its own renderer to provide isolation. In Chrome, a “ renderer” is a process responsible for taking an HTML document, parsing it, constructing its render tree, and painting the result to the screen. ) and some Chrome features will trigger NoState Prefetch provided that the following two conditions are met: a) the user is not on a low-end device, and b) the user is not on a cellular network.Ī new, dedicated renderer is created for the NoState Prefetch. This high memory consumption makes it unsuitable for low-end (i.e. Increasing the size or volume of fetches does not have a significant effect on the amount of memory consumed by NoState Prefetch.īy contrast, prerendering typically consumes 100MiB of memory and memory consumption is capped at 150MiB. Maintaining the preload scanner is the primary memory expense for NoState Prefetch and this cost remains relatively constant across different use cases. NoState Prefetch only uses ~45MiB of memory. There were two primary motivations for introducing NoState Prefetch: This article explains how NoStatePrefetch works, the motivations for introducing it, and instructions for using Chrome's histograms to view stats about its usage. If you’re using Chrome 63 or later, your browser is already using NoState Prefetch for features like. The Resource Hints API, as well as the prefetching of pages by the Chrome address bar, are both implemented using NoState Prefetch. NoState Prefetch is not an API but rather a mechanism used by Chrome to implement various APIs and features. The goal of NoState Prefetch is to use less memory than prerendering, while still reducing page load times. Like prerendering, it fetches resources in advance but unlike prerendering it does not execute JavaScript or render any part of the page in advance. In the meanwhile, use Firefox if you can, and check the link here discussing blacklists on WebGL, you may also want to report this as a bug to the developers.NoState Prefetch is a new mechanism in Chrome that is an alternative to the deprecated prerendering process, used to power features like. So you might wanna try something similar for Chromium. I do know that for Google Chrome the command is google-chrome -enable-webgl -ignore-gpu-blacklist

You will have to find a way to get Chromium to start while ignoring the blacklist.

If it is not, this likely because chromium has blacklisted the RPi's GPU which is why you are getting the following prompt **failed to retrieve device information**īecause your Pi's GPU has been blacklisted. Most people report the issue to do with their graphics card, you can see this issue by going to chrome://gpu/ and seeing if hardware acceleration is enabled for WebGL.

Afterwards, uninstall then reinstall chromium to see if anything has changed: sudo apt remove chromium-browser

Test and check each driver accordingly for function.

You might wanna check your chrome://flash page, and see if you are using any drivers that you shouldn't. Seems like your not the only one with this problem.
