Remove CardView Overdraw

Question

I ran the 'Debug GPU Overdraw' tool on my app in an attemtp to reduce the amount of overdraw. As seen in the image below, the cardview acts like an extra layer of overdraw. I haven't given any additional background colors or images to my other layouts.

Is there a way to solve this?

Answer 1

This might be a misconception, because this is not some "overdraw", but hardware layers are being displayed greenish. In case you really want to disable that, just disable the hardware acceleration for the View (or even the whole application, altogether):

cardView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);

I mean, you could try to disable it once to see that the greenish overlay is gone and then remove that instruction again, in order to switch the hardware acceleration back on. If it may lag, this likely has another reason; for example: a RecyclerView in combination with a ScrollView may lag dearly, when they're mis-configured.
