Describe the bug

As described by kurozer0 on Discord:

I was not using autoTDP yesterday when it happened. I've switched all of my profiles to a custom power preset with no other features just to help test the freezing OS issue. The stuttering seems to be related to time as it's only noticeable after 30 minutes when it starts. Once the issue starts it continues to get more severe. I suppose I should leave it on for hours with the stutter to see what happens. It seems to be related to using the controller as leaving the system idling in a game for hours doesn't cause stuttering. It may be related to unplugging/plugging in the power cable as I've had it start the moment I plugged in the power. Also, yesterday, my game was running for several hours with no issues. I was playing on and off while I was working. I unplugged to move to a different room. The stutters began within 30 minutes.

Other things I've noted:

There is a little frame time spike whenever HC is running and power is plugged/unplugged
The stutters are system wide as moving elements of the desktop, scrolling webpages, and changing games also stutter.
System temps, CPU, GPU, RAM are all normal
HC CPU and RAM are normal

Things that don't fix the stutter:

Changing resolution or refresh rate
Plugging/unplugging external monitor
Hide/unhide/disconnect virtual/physical controllers
Changing power presets
Closing/opening RTSS

Thing that do fix the stutter:

Closing HC
Hibernating system

Screenshots

There is an RTSS .ovl overlay option to show this more clearly.

I am having the exact same issue for months. It is not yet fixed on legion go. I have been tweaking settings but haven't found a solution yet, even including clean windows installation. This bug has prevented me from using HC, and hope it get fixed soon.

Hey @nyavana we'd love to fix this one but we dont know how to reproduce it or what is causing it. Do you have any idea?

thanks for the reply. I am happy to provide any log / dump / event viewer / video or additional information, but unfortunately I have no idea whats the root cause of the issue. Sorry for the format, I wrote it on legion go touchscreen.

Apart from things tried by @kurozer0 above, I have tried the following:

• fresh windows 11 install
• Changed bios vram options
• changed amd gpu driver to 7840u
• Tweaked all settings related performance in hc
• disabled sleep / hibernation
• Possibly other things I can't recall

Here are some characteristics of the issue:

• only happen sometimes after clean reboot, from a few hours to after 20+ hours cpu run time. Maybe depending on how often / intensity I use the device. However, it will definitely happen, just a matter of time.
• Stuttering gradually increase in frequency and duration, until it is totally unusable that for every few seconds, there will be one that last maybe 100ms.
• It occurs on system level and not application dependent. Browsers, games, including file manager are affected
• System input does not break when stuttering occurs. So maybe a rendering / driver issue.
• I always start noticing stuttering getting sever at certain point, not sure if it's just me not noticing it before or it suddenly began to behave this way
• open and exit hc quickly after reboot will not trigger the stuttering
• I only sleep and never hibernate system. Since @kurozer0 says hibernation solves it, this might be the reason why many people don't experience it. I can not confirm if hibernation can solve it but will definitely try it in the future.
• I use legion go primarily as a tablet. When I turn on the device for a few hours with hc and compare to hc disabled, scrolling with touchscreen start to be slightly less responsive with blur, similar to how you play game with inconsistent frame time. I don't really feel it with mouse and keyboard or controller emulated mouse which are less sensitive to scrolling responsiveness.

How is CPU/Memory usage from HC when you start noticing those stutters ?

I can not observe any cpu, ram, or gpu spike when stuttering occur on windows task manager. It might happen regardless of tasks I do, even browsing chrome for a whole day with little cpu usage.

Could you monitor the TDP and Temperatures with HWiNFO when the issue arise ? I'd like to see if either of them are fluctuating.
