The TEST FakeInput request is sent just fine (and produces just a single w here). Thus, not a xcb issue. Reassigning to the server. Confirmed that it's an xorg problem. I downgraded xorg from 1.15.0-5 to 1.14.5-2 and now I get a single 'w' key: [2014-01-18 11:41] [PACMAN] downgraded xf86-input-evdev (2.8.2-2 -> 2.8.2-1) [2014-01-18 11:41] [PACMAN] downgraded xf86-input-synaptics (1.7.3-1 -> 1.7.2-1) [2014-01-18 11:41] [PACMAN] downgraded xf86-video-intel (2.99.907-1 -> 2.21.15-1) [2014-01-18 11:41] [PACMAN] downgraded xorg-server (1.15.0-5 -> 1.14.5-2) I can trigger the issue by pressing *shift* while the example program is running. Confirmed with xserver-xorg-core 2:1.17.1-0ubuntu3 on Ubuntu 15.04.
However, I've found this bug report when trying to figure out why XCB_KEY_RELEASE just after XCB_KEY_PRESS would not output _anything_ (when using awesomeWM's root.fake_input wrapper).
> I can trigger the issue by pressing *shift* while the example program is running.
The example program does not run long. Pressing Shift afterwards changes the "w" chars being inserted to be uppercase for me.
Changing the example as follows makes it work:
dpy = xcb_connect(NULL, NULL);
xcb_test_fake_input(dpy, XCB_KEY_PRESS, 25, XCB_CURRENT_TIME, XCB_NONE, 0, 0, 0);
xcb_test_fake_input(dpy, XCB_KEY_RELEASE, 25, XCB_CURRENT_TIME, XCB_NONE, 0, 0, 0);
xcb_flush(dpy);
sleep(1);
xcb_disconnect(dpy);
Adding `sleep(1)` after `xcb_flush` and before `xcb_disconnect` appears to have an effect.

Created attachment 92349 [details] Compile as: gcc -o xdo -Wall -lm -lxcb -lxcb-xtest xdo.c The xcb_fake_test_input XCB_KEY_RELEASE call is being completely ignored. Please compile and run the attached program illustrating the problem. The program should only output 1 'w' letter, but it outputs 'wwwwwww...' continuously until I press a key. I initially submitted this problem on the XCB mailer list, but Ran Benita wasn't able to reproduce this issue and recommended that I open a bug with my system details.
