Bug 243588

Some Issues with Wacom Tablet (CTH-670)

Problem:
The problem happend after upgrading from the latest R11.3 release to R12.1 release.

Let me say, my wacom tablet (Bamboo CTH-670) is working in generally except for some applications like VLC and Virtualbox.

What does it mean does not working for VLC and Virtualbox ?

Let me explain.

Starting VLC first the wacom pen is working, i can navigate through the menu (Toolbar, Sidebar, etc).

After loading a list of files (ex. a directory, a m3u file, multiple video or audio files) navigation using the pen is no more possible. It is not possible to select a file with the pen or navigate through the toolbar, etc.

It seems that the mouse pointer does not match the wacom position of the pen.

I have a video, but it it not allowed to attached it. The video points it out. After loading a list of files the mouse pointer is 9 rows above the pen position.

If I use a mouse instead of the wacom tablet, everything is fine.
The problem seems to be related to the wacom driver.
