Originally created by @ChrisG683 on GitHub (Sep 12, 2017).

So I've been struggling with the Pixel Launcher on Android 8.0 Oreo lately on my Pixel XL, and I've finally discovered why my launcher was so laggy/stuttery/janky, it's the auto-fill techniques used by password managers such as Lastpass and Bitwarden.

I discovered this through other people realizing it was Lastpass accessibility service causing their launcher to have so much stuttering, so I tried disabling the Bitwarden accessibility service and it immediately cleared up the jankiness I was getting.

I know 8.0 provides the new auto-fill API that should hopefully replace the accessibility service, but I thought I would go ahead and mention this here in case the bug can be hotfixed in the meantime before the auto-fill API release lands.

Seems like maybe the launcher is sending a lot of accessibility events that are slowing things down. Any idea how I can get the launcher on a Nexus 5X to test with?

@carlylemiii I don't get any laggy stuttering with Launcher3 installed. Seems to work well.

Trying a blind fix here. Can you try the new beta version on Google Play (v1.9.0 build 940)? I added a possible fix that will filter out any package name that contains "launcher" in it from the accessibility service processing.

I enrolled in the beta and received 1.10.0 (941). Enabling the accessibility service still resulted in the Pixel Launcher being very janky. On a side note, this does not seem to impact Nova Launcher.

It fails to install, maybe it conflicts with the real Pixel Launcher?

I'm not an Android user so unfortunately I'm not really familiar with that stuff. Any idea when it is suppose to be available to download through normal system update? I thought it was already released a couple weeks ago?

It was, but sometimes they roll it out in phases, I'm afraid I don't have an ETA for you. Also if you're rooted or have your bootloader unlocked, I believe that disables OTAs.

@chetgurevitch commented on GitHub (Sep 21, 2017):

Xamarin support for the new Android Oreo APIs just landed and obviously the pixels are receiving android 8.0.0, so this is kinda a moot issue in the long run but I can replicate this on my nexus 6p as well.

@kspearrin As I'm sure you noticed the play store listing has a compatibility whitelist so people have been extracting it manually from the Pixel factory images. Here's the apk, a couple array values were tweaked to get circular icons working on nexus phones but it's otherwise identical. After extracting the archive you can install it with adb install NexusLauncherPrebuilt.apk or by transferring the apk to your device and opening it with a file manager. The google now page to the left of the home screen doesn't work when it's installed as a normal app but I doubt that's relevant to this issue.

Cool, here's the script https://gist.github.com/chetgurevitch/1c61153f8d37cb8e8f31fd3730e39f6f.

Tested on arch and ubuntu. You'll need zlib1g-dev to satisfy the /usr/include/zlib.h dependency on debian based distros. Also a small tool called simg2img is neccesary (the script downloads and compiles the source from google's android repo) and sudo is unfortunately necessary to mount the images.

I get 5aed0d0bdff8d83b387881126deb31d8c8d139b8708f543ac55687c7fa342a2a as the sha256 sum for the apk, no difference between pixel/pixel xl images. Let me know if you've got any concerns.

Experiencing the same thing. See my comments at https://www.reddit.com/r/GooglePixel/comments/768qor/pixel_launcher_performance_issue_since_oreo_update/. Nova launcher is completely smooth in contrast.

@kspearrin Sorry for taking so long to get back to you on this, apparantly the older pixel launcher won't install as a user app. Luckily the newer version shipping with the pixel 2 does, but pixel 2 factory images aren't out yet. You could download it from apkmirror and use keytool -printcert -jarfile foo.apk to verify that it's signed by google and the certificate fingerprints match those of the apk you extracted before, but if you'd rather wait I'm expecting the old script to work fine on pixel 2 factory images. Those should drop in the next couple days/weeks (10/21 last year). Also the issue is still very much reproducable on the new version.

Ok, I got the pixel launcher installed on my Nexus 5X now from api mirror. However, on this device I do not see any stuttering when the autofill service is running. Seems pretty smooth to me.

While debugging the autofill service, I do however see that this launcher is sending WindowContentChanged events every time the user interacts with it (is scrolls through apps or whatever). I am guessing that is what is causing issues for people since it's a constant stream of event spam to the service. In this case, the autofill service does no work, however, since one of the first checks is if the event is coming from a launcher, so it returns early.

I am not really sure what else can be done.
