I use a Sony Vaio Tap 11 (Intel based tablet) with Debian Gnome, but experience the same issue under Ubuntu, Arch, Fedora etc. .
This tablet has a radio keyboard with touchpad and two buttons connected by magnets.

When I press one of the mouse buttons xinput detects the button press, but after physically releasing the button xinput does not detect any button release. This is the case for both mouse buttons and clicking on the mouse pad. When I suspend and turn on again with running xinput test, xinput detects both buttons released.

I made sure that synaptics is deinstalled (was installed automatically, but not used). => no change
I checked which libinput packages and found that libinput5 is not installed and also not available via apt-get.

libinput-bin/stable,now 1.6.3-1 amd64 [Installiert,automatisch]
libinput-dev/stable 1.6.3-1 amd64
libinput-pad-dev/stable 1.0.3-1+b1 amd64
libinput-pad-xtest/stable 1.0.3-1+b1 amd64
libinput-pad1/stable 1.0.3-1+b1 amd64
libinput-tools/stable 1.6.3-1 amd64
libinput10/stable,now 1.6.3-1 amd64 [Installiert,automatisch]
xserver-xorg-input-libinput/stable,now 0.23.0-2 amd64 [Installiert,automatisch]
xserver-xorg-input-libinput-dev/stable 0.23.0-2 all

Here what xinput shows after pressing button 1, moving around on the mousepad, suspending and turning on again:

ck@CKsVaioTap11debian:~$ xinput test 17
button press 1 
motion a[1]=807 
motion a[1]=808 
motion a[1]=810 
motion a[1]=813 
motion a[1]=815 
motion a[1]=817 
motion a[1]=819

motion a[0]=1523 a[1]=823 
motion a[0]=1525 a[1]=825 
motion a[0]=1528 a[1]=826 
button release 1 

And here the xinput output:

Does anyone has an idea what I can do to get the mousebuttons to be released after press?
Under windows and old Ubuntu distris the mouse buttons worked properly. Also with an older debian live system the mouse buttons worked, but not after I installed that distri. Clicking the touchscreen works as expected. Mouse attached via usb (e.g. logitech) works also as expected. Had a look into gsettings does not show anything unexpected:

gsettings list-recursively org.gnome.desktop.peripherals.touchpad
org.gnome.desktop.peripherals.touchpad send-events 'enabled'
