all kinds of switching between apps (home button, square button) lag a lot and sometimes glitch after update from 2.0.0 to 2.1.1

since the upgrade to 2.1.1 (the latest F-Droid version at the moment)

the home button (the disc that brings back the unlauncher) and other buttons of that menu lag a lot testing it and comparing to 2.0.0 - it adds some delay before the switch starts right away (no matter if it's with animation or w/o thanks to "Remove animations" setting - smartphone pauses before it even begins)

this lag varies and seems to grow over time, the delay can reach many seconds (until I realized that, I thought that tap is just ignored and would tap again and again), making smartphone partially unresponsive at some point

also sometimes there're glitches, like:

• instead of just fade, it goes back to unlauncher with some slide transition (completely unrelevant and confusing)
• white bg is displayed before the switch (i use the midnight theme)
• after tapping an app name in the shortlist, instead of this app getting launched, the notifications screen is opened (the one that you can get to by swiping from the top)

downgrading to 2.0.0 completely solves all these problems but it's kind of sad because 2.1.1 has the long awaited fix of the full-width tap area of every option in the menu! other great improvements too, but that one is what is difficult to give away

Yikes! This is disappointing! Can I ask a few more clarifying questions to hopefully aid with re-creation and fixing this issue?

• What version of Android are you using?
• Roughly how many apps do you have installed?
• What model of device is this on?

yeah, sorry, phone details:

my apologies - apparently those secondary glitches I listed happen in 2.0.0 too but they are not frequent and so minor that i never paid attention to them, until they were emphasized by the lags in 2.1.1

I can confirm the same problem with delay or lag since the upgrade to 2.1.1 on Motorola moto g62 5G (XT2223-1) android 13.

I have noticed an increased lag recently too. On Samsung S22 running Android 14 and Unlauncher v2.1.1

I particularly notice it with the home button when I'm trying to exit an app. Sometimes the stock wallpaper even flashes on screen momentarily before the solid color background of unlauncher loads.

I am a new user, and noticed an unexpected lag for such a launcher. I thought it was native Samsung issue though.

I downgraded to 2.0.0 on f-droid and can confirm that this version is significantly snappier than the latest version.

Same here,

Otherwise I love the app, thank you for your effort!

:+1: Hoping to have some time in the near future to dig into this some more. As a note to my future self (or to anyone else who gets a chance to look at this), I think a good place to start would be to look at the various notifyDataSetChanged calls. These are noted as being bad for performance.

Maybe it could help to have a central settings-class (e.g. as a singleton) to hold all the app settings as a proxy? So read options from that class and have that class sync writes with the settings store. Could help with backup and restore of settings and make it easier to change the storage when android changes the prefered way to do so again.
