Screenshot leads to lipstick high CPU and battery drain

Bug Reports

#1

REPRODUCIBILITY: 20% (occurs weekly) / 100% (screenshot method)
BUILD ID = OS VERSION: 4.1.0.24
HARDWARE: XA2 Ultra, X10 II
UI LANGUAGE: Finnish
REGRESSION: Yes, kinda

DESCRIPTION:

I have been experiencing sudden and unexplained battery drainage overnight with my XA2 Ultra, and now with Xperia 10 II, too. When I have looked at htop it has every time been lipstick process (with a long list of parameters) that is stuck. This can drain some 50%+ of the battery on my XA2 and just last night ~25% of the battery on my Xperia 10 II.

I am quite sure this happened with 4.0.1, too, but I’m not confident enough to tag it.

PRECONDITIONS:

Unknown.

STEPS TO REPRODUCE:

Keep using the phone for a day or two
Edit: Take a screenshot.

EXPECTED RESULT:

Lipstick process acts normal.

ACTUAL RESULT:

Lipstick process gets stuck and consumes ~16.8% CPU the whole time, preventing sleep mode, leading to battery drainage.

ADDITIONAL INFORMATION:

Rebooting home screen doesn’t work, as lipstick is too stuck. Power cycle fixed the issue, until it appears again.

[4.5.0.18] (still) battery drain on XA2

I just triggered this by taking a screenshot!

I had WhatsApp open, I opened toeterm and htop to monitor the situation, and took a screenshot of the screen for test. Immediately lipstick started to consume CPU, and minutes later, it’s still up. The full command is:

/usr/bin/lipstick -plugin evdevtouch -plugin evdevkeyboard:keymap=/usr/share/qt5/keymaps/droid.qmap --systemd

For diagnostics’ sake, I turned off autostart of Android app support, and removed the two culprits I am suspecting: Whisperfish and Battery Buddy. I restarted the phone, started fingerterm this time, and boom - Lipstick consumes roughly one CPU core again.

I tried to restart homescreen using Jolla Utilities, but that resulted in a frozen image. I could long-press power button, and tap the general area where the power button should be, and I was able to power off the device gracegully. Now very interesting…

I’m going to test this with my XA2 Ultra later today.

When I restart the home screen, the X10II just glitches itself out the door. XA2U works fine. Edit: XA2U home screen restart works after triggering the bug, and it also fixes the bug - only to be re-triggered by taking another screenshot…

Both X10II and XA2U can be triggered to battery draining lipstick by taking a screenshot.

The following do not suffer from this screenshot behavior:

  • Jolla Phone (2.2.0)
  • Jolla Phone (3.4.0)
  • Xperia X (4.1.0.23)
  • Xperia X (4.1.0.24)

My plain XA2 is running another OS at the moment, so I can’t test that one.

There was a problem in restarting lipstick on X10II. This has been fixed to the upcoming OS release 4.2.0. With that, by taking a screenshot, I cannot trigger the lipstick process higher than to about 10% (of CPU) and for few seconds only.

Great, thank you! Let’s wait for 4.2.0 then!

Should it fix XA2, too?

#6

It looks like the issue occurs by just using the phone… I have had to reboot my phone five times already and have to do it once more… Nothing fancy going on; Firefox, Storeman (browsing and reading comments), WhatsApp, Deezer, SMS phone calls… I really hope this has been fixed properly, as the battery drainage is substantial.

#7

Hi direc85, can you try Project: sailfishos-notification-preview-high-cpu-usage-patch and let us know if it works for you too?

#8

I’m still at 4.1, because of Whisperfish, so I tried the patch (by commenting the line), rebooted, took a screenshot, and it worked. No more CPU suckage! Just before that, I took a screenshot and it resulted in high CPU usage… So yeah, it seems to fix the issue…!

#9

This bug still exists in 4.2, but at least I can reboot lipstick now :slight_smile:

The patch above still fixes the issue.

#10

This should still be investigated by someone from Jolla IMO

#11

The high CPU item still exists on 4.2.0.21 final, and the patch is needed to avoid it.

I unmarked the solution as to make it clear that the root bug still exists.

Is the patch @vlagged linked already in upstream? I have a Xperia II 10 with SailfishOS 4.2.0.21, and I’m suffering from the same bug as @direc85 is.

Looks like Patchmanager doesn’t work with AArch64 yet. How can I apply the patch until it gets mainlined or Patchmanager gets updated?

#13

There’s a prerelease version of patchmanager 3.1 in chum:testing[1] - you can try that before it hits Openrepos

Thanks! Though I already managed to apply it manually.

I’m not familiar with OBS on SailfishOS. I guess I’ll have to look into it later.

#15

Maybe related? Screenshot with vol+/- and from CLI causes reboot - #3 by poetaster

#16

This still affects at least XA2 Ultra with SFOS 4.4 EA

#17

Thanks for reporting this, and for checking it on the latest release.

I’ve created an internal bug report about it and tagged it as “tracked”.

Thanks for creating a ticket for this!

I do have to add that for handful of times, the latest being just today, I have ran into similar issue on my X10II (lipstick using a lot of cpu) without a screenshot being involved. It was fixed by restarting home screen. So, it could be common with certain notifications, or unrelated… I’ll try to reproduce this with the screenshot in a few days time.

#19

Thanks for that. Any further info that we can use to refine the bug report would be helpful.
