Can you elaborate on the “tablet optimized” setting? I’m not sure what to imagine here.

The tablet-optimized taskbar is a new taskbar display mode introduced in Windows 22H2 (Beta and Dev builds).

I see. To be honest, I don’t see much point in trying to fix bugs with Citra on work in progress OS functions. If the issue is still there when this hits the regular Windows releases, that’s when it’d make sense to look further into this.

Ok, I’ll wait the stable release

@SleepingSnake it seems the latest 1848 reintroduced the issue. With the previous (recent) versions I didn’t have issues

So, to be clear, 1847 doesn’t have this issue?

Yes. I’ve just updated to 1849 and it also has this issue

That does not make any sense. The only change from Nightly 1847 to Nightly 1848 is this: jni\native.cpp: Log `g_build_fullname` on Android by SachinVin · Pull Request #6318 · citra-emu/citra · GitHub
It’s a change that only affects Citra Android, and what it does is this:
Changes what Citra writes to the Citra Android log file so that we can see what Citra version users are using.

It literally cannot affect anything other than that specific logging feature. Please double check whether Nightly 1847 does not have this issue.

Just tested.
1847 GPU usage while playing: <=90% most of the time
1849 GPU usage while playing: 90-100% most of the time

Regardless, this isn’t an issue with Citra. Like I said, there was only one change between the two builds, and that doesn’t even affect Windows. It’s purely for Android.

Besides, is this feature in regular Windows 11 builds yet? I don’t see where to enable it. So if this is still one of those dev/beta features, what I said a couple months ago still stands:

Actually yes, it has been released 3 days ago as an optional update in Windows Update for stable builds:
The Window 11 February 2023 feature update is here, this is what’s new | Windows Central

Basically, if you have the search input in the task manager you also have this one

Alright, I’ll go see if I can reproduce this then. I’ll let you know how it goes :slight_smile:

Ah, Windows disabled the ability to use or test this feature without having a touchscreen supported device. So I’m unfortunately unable to test this. I’ll try to ask internally to see if we have someone else with compatible hardware available.
