[Bug]: Wrong touching position

[numberokta]

Problem description

When touchMode is Simulated touchscreen and Reseed is true and soft keyboard is open, makes touching in wrong position

What steps will reproduce the bug?

touchmode='Simulated touchscreen' Reseed=true open soft keyboard touching the screen simulates touching in the wrong position

What is the expected behavior?

I think touching display size does not change when soft keyboard is opened and display scale is changed and it must be fix

I can not reproduce this. Can you record your screen with show taps and pointer location toggles active?


[numberokta]

you first must open soft keyboard and then run

PATH=/data/data/com.termux/files/usr/bin termux-am broadcast --user 0 -a com.termux.x11.CHANGE_PREFERENCE -p com.termux.x11 -e touchMode 'Simulated touchscreen'

from terminal in termux-x11 while soft keyboard is open. now close soft keyboard and touch somewhere

It's not long tap release, it's tap release and it just get wrong touching position because of changing display scale after closing soft keyboard. the new version is so much better and have more feature and still under developing.

First i show that in Trackpad mode everything's ok and then execute command to change touchMode to Simulated touchscreen and then tap on screen while soft keyboard is open, then i close soft keyboard and tap on screen and as you can see touch point and cursor position is not same

I can reproduce this when display resolution mode=custom/exact and touchscreen input mode=simulated touchscreen. when toggling soft input, somehow LorieView.mSurfaceCallback.surfaceChanged() is not called at all. So the transformation is not updated. The only difference I can tell is that

• custom/exact resolution mode: the LorieView is scaled with a fixed aspect ratio
• native/scaled resolution mode: the LorieView always tries to strench to fit the screen, so the aspect ratio is changed

maybe it's better to call LorieView.triggerCallback() manually when toggling soft input?

Again. The topic is "Wrong touching position" and topicstarter described it pretty clear: when he uses specific touch modes and toggles keyboard position of cursor is wrong. No lost gestures. Another user even found the reason of this: LorieView.mSurfaceCallback.surfaceChanged() is not called because surface size was not changed. Next time you post off-topic message it will be deleted immediately. Older off-topic messages will be deleted immediately too.
