OnePlus 5's Display Is Inverted - Cause of Issue

by Hilbert Hagedoorn on: 07/03/2017 07:38 AM | source: | 9 comment(s)

Last week we reported about the new OnePlus 5 being plagued by what is now called the Jelly Scrolling effect. The problem has been identified, they installed and thus mounted the display panel upside-down on the OnePlus 5.

The company insists that this was intentional and not an oversight, yet it is resulting in an annoyance dubbed "jelly scrolling": this effect causes text to bunch up together and then stretch out when the user is swiping in the opposite direction. There will be no OTA update or RMA to resolve the issue.

OnePlus fiddling around with a super laggy display problem on its flagship, and claiming it’s “natural effect” and normal, come on now.

That is not truth. Mounting has no effect on buffering method. Enabling vsync will guarantee 100% correct image.
Unless this is error in software based buffer. (Which is quite likely as hw buffers issues are not that huge due to limited refresh rate.)

Then that UI is pretty laggy. Input lag is huge. Which looks like they are overloading another buffer.
And then i smell improper memory region locking.

It's an AMOLED display, it has a super retarded subpixel layout, it may not be the same thing exactly upside down as it is rightside up depending on what type of AMOLED it is. It can be actually off by a row or more of subpixels causing a bunch of anomalies.

For the record that can also happen with an LCD, but it's just more likely to have problems on a dumb pentile layout.
Have you seen that video? No display can do that on its own. Because no display has thousands of buffers.

This looks like vsync issue when you throw hundreds/thousands more images into it than it can handle.

Start HL2, unlock fps, and let your GPU scream for a while. You'll see exactly same thing. Only it works from side to side. As LCD monitors run refresh vertically, but many tablet, phone screens run it horizontally if placed in landscape orientation.
