How to fix Green and Purple videos in Google Chrome
If some of the videos you view in Google Chrome are being displayed in green and purple colors it could mean that your Google Chrome GPU process is not composing accelerated media related content properly. Perhaps the GPU process was somehow ended which resulted in Google Chrome generated HTML (HTML5) videos and other graphics with overlapping green and purple colors. If the GPU process is not running correctly in Google Chrome it will cause HTML, CSS, and various types of graphics to fail inside the browser window in normal and incognito mode.
The GPU process is a Google Chrome process that is used by the internet browser to display GPU-accelerated content such as videos and graphic files with high pixels (for example, .gif files). The GPU process also serves other purposes; The process can help reduce power consumption and limit battery usage for multiple devices because it takes less power than CPU.
In a document published by Tom Wiltzius, Vangelis Kokkevis & the Chrome Graphics team they state that web browsers traditionally relied on the central processing units to render graphics. But now with graphics processing units being an integral part of popular devices (laptops, tablets, smartphones, etc.), attention has turned to finding ways to effectively use this underlying hardware to achieve better performance and power savings.
GPU can achieve far better efficiency than the CPU (both in terms of speed and power draw) in drawing and compositing operations that involve large numbers of pixels. – Chromium.org
There are several solutions and troubleshooting options that can help you find the appropriate answer to fix green and purple videos and display normal SD and HD videos and graphic content in Google Chrome.
