Touchscreen issues with debian12

Trying to get the Rpi Bookworm version fully working, and discovered that double-tap click doesn't work.

Figured this would be trivial. Started googling, then saw where Rpi 5 users are still complaining theirs do not work either. Found a few things which seemed interesting, like adding Option "Gesture" "off" to 40-libinput.conf (resulted in black screen at login) and disabling from config.txt the line dtoverlay=vc4-kms-v3d... the desktop background and resolution changed, but no double-click. Then tried changing the active one to dtoverlay=vc4-fkms-v3d and saw a brief blue flash during boot, but otherwise still the same.

Somebody more familiar with libinput may have to chime in. I even sent a support request to Waveshare (my touchscreen vendor) so maybe they will come up with something. But this is a huge issue, even affecting the official Rpi touchscreen.

Edit: Waveshare responded that they are aware of the issue and are waiting on Rpi /Debian to update drivers.

I can also confirm that double click on touchscreens does not work in Debian 12 with xfce. It googled it a bit and it seems to be an upstream issue.

Same problem here with hanspree touchscreen and debian 12.
Any solution?
If install cinnamon instead xfce ?

I have not seen any solution posted on the xfce website so far.

I have installed touchegg and i can set gestures like tap with 2 fingers for emulate right click or pich zoom unzoom but i don't think this is real multitouch function

apt install touchegg

and add these to file /usr/share/touchegg/touchegg.conf

  <gesture type="TAP" fingers="2" direction="">
                        <action type="MOUSE_CLICK">BUTTON=2</action>
                </gesture>
 <gesture type="TAP" fingers="3" direction="">
                        <action type="MOUSE_CLICK">BUTTON=3</action>
                </gesture>

<gesture type="PINCH" fingers="2" direction="IN">
<action type="SEND_KEYS">
<repeat>true</repeat>
<modifiers>Control_L</modifiers>
<keys>KP_Subtract</keys>
<decreaseKeys>KP_Add</decreaseKeys>
</action>
</gesture>
<gesture type="PINCH" fingers="2" direction="OUT">
<action type="SEND_KEYS">
<repeat>true</repeat>
<modifiers>Control_L</modifiers>
<keys>KP_Add</keys>
<decreaseKeys>KP_Subtract</decreaseKeys>
</action>
</gesture>
 

I have tried a lot of live linux distros to verify if touch screen works.
In debian 11 has the same behavior as debian 12 so it is not software regresion.
All distros i have tried with xfce have same behavior with debian except fedora
that inside firefox you can pinch in - out for zoom unzoom and copy text with extended taping inside xfce double click on desktop also not work also on fefora.
In fedora with gnome3 seems to have better support for touch that fedora xfce.
Here says multitouch handled by toolkit or composer

Multitouch gestures can be handled in debian 12 xfce by touchegg very good
but the problem are not the gestures us the double click and tapping for extended time to emulate right click.
