Hello and welcome to justanswer. My name is***** will be assisting you today. I am sorry to hear that you are having such trouble.
Please try to disable GPU and test it again.
Step 1. Open Google Chrome and click the three horizontal lines icon to the far right of the address bar. Now choose Settings.
Step 2. At the bottom of the page click on 'Show advanced settings…'
Step 3. Scroll down the page again until you find the System heading, below which is an option to 'Use hardware acceleration when available'. Remove the tick from this box to turn off hardware acceleration (or tick the box to turn it on).
Step 4. Having altered this setting you'll see a link pop up beside the option advising that Chrome requires a restart. Tap restart on this link to restart Chrome with or without hardware acceleration.
We need to test Chrome first with GPU disabled and if it still occurs we can test with Safari and if Safari works it can be
extensions in Chrome causing the issues.
You can test your hardware with the AHT test
Note: Your test results will appear in the window in the bottom-right of the console.
