Intermittent bug where the updates to the screen when scrolling or searching are not rendered

[codeinabox]

I'm experiencing a bug where the updates to the screen when scrolling or searching are not rendered. Yet if I touch the screen, the app opened is not the one that appears on the screen, but instead the one that would be listed if the rendering wasn't frozen. Sometimes this bugs goes way, but most of the time I have to force stop the app. 

Happy to help you diagnose this, what information do you need?

Hmm, I dont think I can even influence which item is selected -- the whole thing is a standard Android list and it work the way it works. The only thing that could be fixed is to update faster so that there is no stalling. For both scrolling and searching, however, there is not much stalling on my phone. For searching, maybe a fraction of a second. Do you have particularly many apps or a large number of contacts to be searched? It will be slower then, of course, and maybe too slow. I spend no effort searching in background or in another thread, but it is indeed implemented as stop-the-world.

Sorry I don't think I've described the problem very well and a video might better illustrate this, it's not that updates to the screen are slow, it's that they stop.

For example, if I scroll through my apps the list doesn't move, and if I click on an app a different one will open, so effectively it is scrolling but the screen isn't updating.

So if it stops, it won't continue to scroll a while later? It just stops? Not temporarily to compute s.t. for a while, but for good? And then no matter how long you wait, when you touch an item, it opens the wrong one, because it did not show you the current state, but an old state of the scrolled list? So it's like a screen update after scrolling is missing and will not show, ever? Do I understand this correctly? If it is so, then I am totally unsure how this can happen.

I have this problem and made a screen recording. I can send via email.

This bug is not unique to this launcher app, I've also seen the same thing happen in Olauncher tanujnotes/Olauncher#572
