Info

Expected Behavior

The device should swap screens seamlessly without losing touch input between single/dual postures

Current Behavior

Any transition from a left screen posture will lock the screen up and prevent touch unless a reboot is performed, or a pen is used on Surface Duo 2. As seen in Archfx's GIF demonstrating the new feature, we can see that this does not affect Surface Duo 1, as he seamlessly swaps from Left -> Right -> Dual Screen without the touch locking up.

This is an extension of #50 . However, we now know it's just the left transitions, never the right or dual transition.

Possible Solution

Something in the way we set the display composition for left screens may be weirdly set, perhaps the negative panel offset?

Steps to Reproduce

1. Set the option "Default Screen in Single-screen postures" to Left
2. Fold device to show on singular screen
3. Open the device to transition to Dual screen
4. Screen locks up unless pen or reboot is performed.
5. Try again using the Posture locking option in 2024.12.21
6. Transition from auto to manual left.
7. Transition again from left to dual/right, which ever is next.
8. Screen locks up again, Pen or reboot is required.

same for me!

Since updating to v12.23, the frequency of freezing when closing and reopening has increased.
Default Screen is Right.

[plan0495]

In previous versions, when closing the phone, the screen would go dark and both screens would show the clock and battery level.
In v12.23, when closing the phone, only one screen is shown and the clock and battery level are not shown.
If that screen is the left, the touch doesn't work.

Can confirm, when the overlay for the peek mode appears on left only, it breaks the touch input for Duo2.

Either way, for peeking the time, I reckon it should show on both screens. So as a result we should show on both when peeking the screen. However we still need to try fix the left screen lockups down the line.

I would suggest an option to disable using the left screen of duo2 alone before there is a solution to this problem

New issue: with the newest update, sometimes touch completely stops working when opening my duo 2. i disabled the left screen with the settings too.

This is probably the peek mode optimisations that only show on one screen, if the peek mode shows up on the left screen it will lockup the display as expected here.

this happend again, i saw when i folded the duo2 open, for a split second the right screen was inactive and the left one active, i expect this to be the reason.

ok i switched to my pixel 7 now, the duo2 is unusable in this state. 1-5 folds and touch stops working and i have to force reboot, it is too annoying :(

@Archfx also just wondering, why do we Restart the launcher between some dual screen postures? I notice we have some launcher restarts between book and flat postures.

Trebuchet launcher does not correctly refresh during posture change, so the posture processor sends this broadcast such that the Trebuchet can refresh itself. This is related to #49 and #39.

Oh no I get why we have to restart the launcher, but between some cases where the layout should stay the same it restarts anyway, specifically between about 110 deg to 180 deg there's something that feels like a launcher restart.

[Archfx]

That is weird, can you confirm it using the log.

adb logcat | grep RestartReceiver

This should be triggered if the broadcast is sent. My expected logic was to restart between tablet and phone modes.
