Xi2 does not return XI_RawButtonRelease event for any of mouse buttons if clicked over any X window. All what's generated is a XI_RawButtonPress event. Using test program (attached) click with any of mouse buttons on any window. Expected to get 2 events: XI_RawButtonPress and XI_RawButtonRelease. Only one (XI_RawButtonPress) is generated.
This can be tested with 'xinput xinput-xi2' test program from Xorg.
Same reason as Bug 26922, so I'm marking this as duplicate for simplicity. *** This bug has been marked as a duplicate of bug 26922 ***
