Text is blur on scrolling

aier — Thu, 28 Sep 2017 20:28:05 GMT

When scrolling, the text is slightly blurred. This might be down to the low pixel screen?

It is noticeable on, this phone, while on my htc 10 i dont notice it at all

I've had this phone for a day and just noticed this. Didn't have the issue on my Z5C so it's nothing to do with the screen resolution.

Anyone know why this happens?

adjust the graphics in developer options, and you can get better control, and battery life

@NeoBeum May I ask what those development settings are? I am not sure you can change the amount of blur, since that looks like slow LCD crystal rotation speed, not the motion blur effect driven by the OS.

it will be device specific, because you'll need to play around with the color mode and also the gpu rendering.

I don't have the xz, but all devices will use the same graphics library to draw, OpenGLES, 3D rendering works slightly different to 2D when you factor the light effects for the shaders. I haven't got experience for embedded GL so I don't know where the AA will be added for each frame. I have only a limited experience for graphics programming when I did my game development course.

There are basic overrides in developer options to force GPU for 2D rendering that should improve aesthetics but at the cost of battery power, as the device will be using both CPU and GPU to draw

The other setting that could have an effect on pixel AA is sRGB

picture color mode

edit: I'm generalizing here and including the blur with AA as a post processing filter/shader/effect
