Bug Description

I have a wetab tablet, I used ubuntu 12.04 with easystroke 0.5.4 and xserver-xorg-input-evdev 2.7.0 from official repos. I have a strange problem, the focus sometimes changes between windows. For example, if I have a text editor and a terminal opened, click in the editor and write with the onboard keyboard, I expected that my text were written in the editor. However, the focus moves to the terminal and the text is written in the terminal. Clicking in the editor window doesn't return the focus to the editor, but moving the editor window gives the focus to the editor.

It's only an example, the problem don't depend on the editor and the terminal, lots of apps seems to randomly change the focus.

I've tested in the same tablet with Arch Linux, which uses xf86-input-evdev driver with mtdev support, and the problem persists. However, rebuilding the same evdev driver but without mtdev support the problem dissapears. I've noticed that this problem doesn't appear if easystroke is not in use. So this problem seems to be connected to easystroke, evdev and mtdev.

My tablet has an egalax touchscreen. I've read the same problem in a different machine with the same touchscreen: https://bbs.archlinux.org/viewtopic.php?id=147264 Wish this information helps

Only to add that the problem occurs both with easystroke 0.5.4 and with easystroke 0.5.5.1.

Seems like this is the X server's fault, which doesn't generate EnterNotify events on touch input.

Can you check if this is still an issue with 0.5.6?

Hi. Today easystroke has been updated in the archlinux's repos. I've tested with 3 different drivers

- xf86-input-evdev 2.7.3 built with mtdev driver
- xf86-input-evdev 2.7.3 built without mtdev driver
- xf86-input-evdev 2.6.0 built without mtdev driver

I haven't found this issue with any of the three drivers. It seems that this bug is fixed, thanks
