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=807 motion a=808 motion a=810 motion a=813 motion a=815 motion a=817 motion a=819 motion a=1522 a=821 motion a=1523 a=823 motion a=1525 a=825 motion a=1528 a=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:
