Extremely laggy system UI after CM update - X Play Q&A, Help & Troubleshooting

Hi guys,
I've been running CM 13 for a while on my moto x play. I've had no problems with it until this last update and installing some themes.
After updating it, I downloaded some themes, applied them and received the "system ui has crashed" or something message on screen.
After this the wallpaper has turned black (no change if I try to change it manually), the animations for the lower bar (triangle, dot, square) are not showing, dragging the upper status bar takes several seconds to show, when my cellphone is unlocked the response of the system is extremely extremely slow. If I drag my fingers up to unlock it, it will take a long time. The funny thing is besides these, there are no problems apparently. If i go to settings, things run smoothly, chrome, facebook, whatsapp, etc. but any interaction with: status bar, lower bar, locked screen is extremely slow.
I mistakenly thought it was an update bug or smth and reinstalled a past update, but issues remain.
What happened and how can I correct this?

Well you said it yourself that the problems started after applying a theme. Did you try to reset to the system default theme?
Also never downgrade CM versions because that will only cause more problems than solving them.
If nothing helps I would recommend a clean installation because I don't have any problems with CM13 and any themes. Also some themes require a restart after applying.

Same thing happened to me as well. The status bar was not to be seen and there was no wallpaper. Did a clean installation and it was all ok. I am not sure which themes were installed back then.. But if you could share the ones that you installed, it might help!

Notification Bar Sticks & Screen Time Out!!!

I have the newest cyanogenmod 4.2.5 but after a while of my phone being on i notice that i cant pull down my notification bar and even if i press menu from the home screen and press notification it wont come down. Also, i have noticed that my screen while time out and go black in the middle of me scrolling. Can anyone suggest a way to fix this? Thanks
try to reflash
Thanks! but how exactly do i reflash? i just learned how to do all of this maybe 2 days ago so i'm still really new to everything.
Did you install any lock-screen apps? I noticed that when I installed those, sometimes my notification bar would get stuck.
On the other hand, you can reflash by reinstalling Cyanogens rom.

[Q] Status Bar Force Close

Hi Guys,
I recently installed Pure messenger widget off the marketplace. It runs fine most of the time but sometimes when I click on one of the updates, it causes the status bar to force close.
Most of the time the status bar will restart itself but sometimes this does not occur. Is there a way to restart the status bar without having to reboot?

I see this sometimes (but not since I updated to N94). There's an app called "Notification Restart" which doesn't really work like you'd want it to, but it beats rebooting.
If it happens like I've seen it happen then its usually because I haven't rebooted in a couple days. So before I set it down for awhile ill just select reboot and walk away. Then when I come back its ready to go.
Has anyone found a fix for this? I get a Status Bar FC on startup, and it never fixes itself.
I am using the stock ADW launcher, but I have altered the screen density. Could that be it?
It doesn't look like they gonna fix it at all.
This is a very irritated.
Darn. I installed CM7.1 and it FC'd a few times... Then after I altered the density it has not made it past the FC at all in the last 10+ restarts. I might try to reflash CM7.1 just to make sure something didn't go wrong. What a pain.
Also, I tried the tricks that were mentioned about manually restarting the service, using the Notification Restart app, toggling the status bar hide/show option, nothing seems to bring it back up.

What worked for me was getting a pure Sandisk class 4 sd card. I had a class 4 by lexmark before, but would get random fc's on systemui which would make my bar go away.
Now I'm on a 16 gb Sandisk Class 4 and haven't had any fc's since.

Hey guys, I used to have the same issue (happened sometimes with some apps, and always after an LCD density change). What fixed it for me was running "Fix Permissions" in ROM Manager. Run it and restart, and hopefully it'll fix it (it did in my case).
Hope that helps.

[Q] Frozen widgtes and floating navigation bar

I have met a problem that my G2 usually get frozen widgets even i restart my phone or change my theme or reinstall my rom, the widgets will stop after few minutes. The widgets still can press but no light will turn on or change after I pressed it.
In addition, after I have flashed my cwm and install g3 notification panel, my navigation bar kept floating and I have no idea how to make it steady.
Can anyone advise me how to fix that problem? Thank you very much.

[Q] Broken icon background transparency (4.2.2)

I have this issue for a long time by now. I thought it is just the Play Store but no, I noticed it in the facebook messenger too.
Icons and smileys has black background, and in messenger when I use the bubble head thingy, smiley's background is transparent, you can actually see the things behind it, like my home screen wallpaper.
I googled it, but no fix for it, even updated the Play Store. Factory reset did not help. I even replaced the ROM with a new one, but this problem appeared again. (4.2.2, root) I had this problem before the root acces too. I really don't know what to do.
And other forum peeps said the bug only appears on Mediatek devices...
Notice the icons in the Store, and in the Messenger (black background and home screen)
It happens to me too. Its used too be soooo annoying, but I just got used to it. But I still want a fix.
It happens on my phone too and I have no idea why or how to solve it.
I have a Mediatek based phone.

recent apps view issue after system update WW_13.20.10.79_20161009

Hi all,
after the system update version WW_13.20.10.79_20161009 , pushing recent apps button, the view of open apps wasn't as usual like a group of 3D tabs with a wonderful
effect in scrolling among them. but as a flat view. In other words every app appears below the previous, not in 3D style view as usual.
Anyone can help me to understand if this is right after the update, or it 's a misconfiguration of my update or a particular settings that I need to apply ?
Thank you in advance
Roberto
Got the same behavior and found no settings for that. And after a day, I found it OK.
And the notification on expanded status bar sometimes become 3d like recent too
Bought my phone(ZE552KL) 3 days ago(Canada) and today installed a new update called MMB29P.WW_Phone-13.20.10.131-20161028 So while I can't compare since the first I did when I got the phone in install all updates, the background apps list does look VERY 2D and flat like you said. And honestly I'm having a hard time seeing if an app is in the background or in the foreground.
Still ****ing love this phone tho!
