mousepad cursor constantly going to to the bottom left corner of the screen

[Mathieu]

Since I accepted the latest system update from ubuntu, my mousepad cursor goes to the bottom left corner of my screen (opening the trash file, most of the time) when I try to click (with the actual button ; no bug when using the pad itself to click).

Does this issue go away if you boot back into the prior kernel version?

[Joseph Salisbury (jsalisbury)]

Also, would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.8 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.
