Comment 38 for bug 799202

Hmm, looks like we are progressing in what the problem is.

As suggested by Jussi, I tried the tablet sample app from qt4-demos, and I can confirm that pressure works fine.

However in that demo app, when I try to use the "tilt" value from the tablet to set line width (in the Tablet menu > Line width > Tilt), I get some strange results: a rather constant fine line with sometimes a random huge rect appearing. Trying to set the color saturation from the "Tilt" value doesn't work either. The behavior is the same on my Touchscreen and on my Intuos 3 usb.

I tested with the "unpatched" xserver (without the 503 patch), and with this version, setting line width from the tilt value works fine on my intuos 3, and the line width stays fine on my touchscreen that maybe doesn't provide a tilt value, but I never get those random huge rects.

So it looks like the problem introduced (or revealed) by patch 503 may be with the tilt value, not the pressure...
