Steps to reproduce the problem:
On the Samsung Chromebook Plus 2017 Version follow the examples below and take a look at the screenshots attached.  
I have multiple examples: 
Example A:
1. Open Internet browser and go to http://jpwright.net/subway/
2. Click Start From Scratch and enter a city (for this example use Rochester, NY)
3. Once into the main screen there on the right hand bar tap the letter a, then tap anywhere on the screen to build a station.  Click and drag the screen a little bit away and make another a bit of a distance away and a blue line should show up as a subway line there. 
4. Click and rag the screen around a bit to see the issue occur. 

Example B: 
1. Open the browser and go to www.openstreetmap.org Login to edit the map 
2. go to the layers settings and chose mapbox. 
3. Once it is showing, scroll around the screen and watch the issue happen within the ap section of the screen.   

Example C: 
1. In the browser go to: https://www.mapbox.com/maps/satellite/
2. Click on View mapbox satellite streets live. 
3. play around in the map views zooming in and clicking and dragging to reproduce the issue. 

Example D:
1.  go to https://poly.google.com/creator/tours/
2. Begin to build a tour tapping new tour 
3. Type in the new scene section Rochester, NY on the map area. 
4. click and drag the street view showing up and notice the layering issue and banding etc. that occurs.  

What is the expected behavior?
Clear imagery and properly rendered graphics layers.  

What went wrong?
You can see in the screenshots that the graphics are improperly rendering and causing layering issues in various images especially when clicking and dragging them.  However, it also does frequently occur when images are staying still as well.  It does not occur with every image, but especially in these last few examples it is a big issue.   This has been occurring since the first update to 69 on the Samsung Chromebook Plus 2017 version.  

Did this work before? Yes 68 or 67 on Samsung Chromebook Plus 2017 Version

Chrome version: 69.0.3497.120  Channel: stable
OS Version: 10895.78.0
Flash Version: 31.0.0.108 /opt/google/chrome/pepper/libpepflashplayer.so

This has been an ongoing issue that makes it very hard to complete a multitude of tasks on the Samsung Chromebook Plus 2017 version.  It makes it so you cannot see the images and media you need to see because this covers it and when you move the view around, it just follows it and creates more banding, etc.  This has been a serious issue that is making it nearly impossible to do work on the Samsung Chromebook Plus 2017 version.  It may or may not have a relation to whatever is also causing the issues with android apps on the device from displaying proper rendering of graphics layers, etc.  For those of us in the public and private sector who do mapping and GIS work such as for County agencies, etc. , it makes the Chromebook Plus completely unusable for our work.
