Subsequently use following command to pull the recorded file:
adb pull /sdcard/video.mp4
Attach the file to this issue.

in the worst case the complete UI stays laggy even when Chrome is closed. In that case only a complete reboot of the phone will help which is super annoying

For me playing some video in another app fixes the lags in whole system UI

I also have this issue on my Android 14 (not pixel) device.

The issue appears every time a 30fps video is on screen: the full UI is then rendered at 30fps. It can be the case watching a youtube video, or scrolling some apps with 30fps video previews.

In the log:

I DisplayDeviceRepository: Display device changed: DisplayDeviceInfo{"Built-in Screen": uniqueId="local:0", 1080 x 1920, modeId 1, renderFrameRate 30.000002, defaultModeId 1, supportedModes [{id=1, width=1080, height=1920, fps=60.000004, alternativeRefreshRates=[], supportedHdrTypes=[2, 3]}], colorMode 0, supportedColorModes [0], hdrCapabilities HdrCapabilities{mSupportedHdrTypes=[2, 3], mMaxLuminance=500.0, mMaxAverageLuminance=500.0, mMinLuminance=0.0}, allmSupported false, gameContentTypeSupported false, density 420, 403.411 x 399.737 dpi, appVsyncOff 1000000, presDeadline 16666666, touch INTERNAL, rotation 0, type INTERNAL, address {port=0}, deviceProductInfo DeviceProductInfo{name=, manufacturerPnpId=, productId=, modelYear=0, manufactureDate=null, connectionToSinkType=0}, state ON, committedState ON, frameRateOverride {uid=10125 frameRateHz=30.000002} , brightnessMinimum 0.0, brightnessMaximum 1.0, brightnessDefault 0.39763778, hdrSdrRatio NaN, FLAG_ALLOWED_TO_BE_DEFAULT_DISPLAY, FLAG_ROTATES_WITH_CONTENT, FLAG_SECURE, FLAG_SUPPORTS_PROTECTED_BUFFERS, FLAG_TRUSTED, installOrientation 0, displayShape DisplayShape{ spec=1673867177 displayWidth=1080 displayHeight=1920 physicalPixelDisplaySizeRatio=1.0 rotation=0 offsetX=0 offsetY=0 scale=1.0}}

Note the 'renderFrameRate 30'

This was not the case with Android 13.

Daily up.

Some info which can be helpful:

• UI becomes more laggy with lesser video frame rate: you can see this on first (video is 15fps) and second (video is 20fps) screen records
• Some of 30fps videos causes UI lags only for the first 5 seconds (see screen record 3, after playing UI lags for about 2 seconds and then becomes normal)
• Some 30fps always causes UI lags (see screen record 4, it's not very noticeable on screen record, but actually UI feels too unsmooth)

Adaptive refresh rate on Pixel was present also on Android 13, wasn't it?

Up!

This bug was fixed in QPR2 beta 3 (at least for me) and should be presented soon in the stable version. Asking to close this issue and 278143266

Thank you for reporting this issue. We have a fix rolling out in the next release.

I also have a Pixel 4a(5G). This is very annoying. It turns out that, like someone said earlier, it likely has something to do with the Adaptive Refresh Rate feature, even though these devices don't support it. Notably, the issue arises when watching video at 30fps, any resolution, any app. If you play a 60fps video, the issue goes away.

I thought that there's probably a way to force the refresh rate without Settings. Did some research and found some ADB commands that appear to work. I ran the following commands on my Pixel 4a(5G) from my PC with "Debugging over USB":

adb shell settings put system min_refresh_rate 60.0 adb shell settings put system peak_refresh_rate 60.0

Interestingly, the issue went away! However, only for the System UI (Notification shade, opening app switcher, home screen swiping, etc.). In any apps playing video, the issue still appears to persist.

I'll attach some screen recordings when I get a chance.

Fix comment:

adb shell settings put system min_refresh_rate 60.0

adb shell settings put system peak_refresh_rate 60.0

I should also note that these changes don't appear to persist after rebooting the device. So you'd have to run them on each startup.

If this issue still exists in a current Android build, we request that you log a new issue along with the bug report here https://goo.gl/TbMiIO and reference this bug for context.

@comment#138,

The issue 278722571 was raised on the older build than the one which was available on Jan 16th 2025, so request you to follow the instructions in comment#137 which we will pass to internal team for further check.

Thanks.
