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]=808
motion a[1]=810

motion a[0]=1525 a[1]=825

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'
org.gnome.desktop.peripherals.touchpad natural-scroll true
org.gnome.desktop.peripherals.touchpad two-finger-scrolling-enabled true
org.gnome.desktop.peripherals.touchpad left-handed 'mouse'
org.gnome.desktop.peripherals.touchpad click-method 'areas'
org.gnome.desktop.peripherals.touchpad speed 0.0
org.gnome.desktop.peripherals.touchpad tap-to-click false
org.gnome.desktop.peripherals.touchpad edge-scrolling-enabled false
cat /proc/version

No clue if this works for you, but my laptop+mouse sometimes suffer the same problem and I accidentally found out it can be fixed by tapping the touch screen once. Afterwards, the mouse works as expected and the button gets released again.
Worth a try I think :)
