![]() From my understanding, with current canvas rendering this isn't an issue because the GPU textures are not being made, the frame images are stored and passed through every frame without the extra step. Videos and GIFs with more frames cause more memory pressure and at some point something is tripping because we are consuming too many resources. New GPU textures will be created on every drawImage call for every layer on every frame. From my understanding the GPU is taking over when we are drawing these images into the canvas with drawImage. Our app is decoding video (mp4) and GIFs in WebAssembly and converting them into JPEGs and PNGs (on the CPU) in workers and then rendering to canvas elements. I'm not holding you to anything but our app is crashing browser tabs because of this features just trying to establish if we should work on this which likely involves some pretty deep rewrites. We are a little unclear about "will remain that way until the final releases ship"ĭoes this mean that when it ships this setting will change or that the setting that is active in the beta usually ships to everyone. The GPU Process: Canvas Rendering feature uses new architecture to support canvas rendering that occurs in a new GPU process instead of the Web Content process. Often, but not always, entries that are enabled by default in a beta will remain that way until the final releases ship. Engineers use the mechanism in released Safari versions to enable and disable features for their own testing needs. They remain in the menu until the Experimental Feature menu support is removed. Safari releases also include the Experimental Features menu with experimental features that are enabled by default. When they are ready to be tested and used, they become enabled by default. They also change frequently with different releases of iOS and updates to the Safari app. Experimental features that are not ready for developer testing are disabled by default. Most of the experimental webkit features are for developers. It also gives WebKit engineers a mechanism to enable or disable certain features for testing during development. I am not familiar with the terms or settings on this list and thus began to switch multiple settings to the odd position. It gives developers the opportunity to experiment with new features, such as HTML5 elements, JavaScript APIs and more, on the native iPhone platform. Experimental WebKit Features Hi when delving into my iPhone settings I came across Experimental WebKit Features and noticed some of the features were switched on whilst others were not. ![]() Options that appear in the Experimental Features menu, though accessible in Safari releases, is most useful for Safari Technology Preview where it allows web developers to try out in-development features and provide early feedback. To use experimental WebKit features on iPhone, you first need to install the experimental version of WebKit on your device. Experimental WebKit on iPhone is a special version of the WebKit engine for Safari that is used for testing of new features before they are released in a more stable version. ![]()
