Pixel Slate Tablet animation storage software fix, reduced memory on Google radar – About Chromebooks



When I discussed a video of the Pixel Slate performance between the $ 799 and $ 999 models, I noticed that the Chrome Team opened a bug report for the horrible animation store on the $ 599 model. It turns out that the team was aware of this even before Pixel Slate started shipping. We know that thanks to Chrome Unboxed, who discovered a similar but different bug report that has been in the works since November 8, specifically mentioning the Celeron model at the entry level.

At least part of the problem of rounded corner has software implementation on the user interface:

A lot of animation jack seems to come from the use of Mask Layers to create rounded corners. This combined with background sharpness adds many more steps to the paint / rendering pipeline. The result (fps increase) and memory enhancement (tiles are not discarded and we actually see the content) is quite important on the Nocturne Celeron when rounded corners are removed.

I assumed the problem was not hardware related, or at least could be improved through software optimization. It may sound strange as the chips in the various Pixel Slate models range from the low Intel Celeron to a Core i7 processor. However, the integrated GPU is actually the same for all models: It is Intel HD Graphics 615.

There is a key difference in the basic level Pixel Slate with Celeron which can also have a negative impact: It is the only configuration with 4 GB of memory. And the memory of all Slate models is shared with Intel HD Graphics 615, so when you start with half the memory of $ 599 Pixel Slate, you're already in the hole. A trace of overview mode showed 1.5 GB of memory in use, for example. This is why in my Pixel Slate Buyer's Guide, I suggested that anyone interested in Celeron-powered Pixel Slate uses the extra $ 100 to get 8GB of RAM; This price also doubles the local storage area.

To be clear: All models of Pixel Slate need optimization when it comes to overview mode animations. It's less of a problem if you have a keyboard attached to the shelf, because you can use the alt + tab to maneuver through open apps and / or you can see more apps on the screen at the same time.

More Chrome tabs, a PWA, Google Play Music Android app and Linux like lobster together.

When using the Pixel Slate without keyboard, you are in the Chrome OS whiteboard mode where only the way to switch apps is to use summary mode and handle laggy animation. In addition, you can only see two apps on the screen at once.

The bug report found by Chrome Unboxed indicates a measurable version of Chrome OS 73, which is not due to land in March. Perhaps people with $ 599 Celeron see early improvements in the Dev or Beta channels, which will be available for version 73 in the coming weeks. Also note that this same animation code is used for all 2-in-1 Chromebooks or Chrome OS tablets, so they can take advantage of any repairs or software adjustments.
