This tip is only for HP TouchPads running webOS 3.0.5 and LunaCE 4.9.5 or higher
Ever since the original Palm Pre was released running webOS 1.0.1, any time you tapped on the screen of a webOS device you would see a "tap ripple" animation to indicate the location of your tap. While it may be nice to know where you tapped on the screen, it can also cause a slight bit of lag on your device, especially in high frame-rate PDK applications. Unfortunately, you have never had any control over the presence of the tap ripple until the release of LunaCE for the HP TouchPad, the homebrew update for the TouchPad by WebOS Ports based off the Open Source "webOS Community Edition" (not to be confused with Open webOS). With a simple toggle in the homebrew Tweaks application, you can now turn the ripple on or off at will.
Note that LunaCE is currently in beta so you will need to go through the process to set-up the beta feeds in Preware, which can be found at testing.preware.org. In addition, you will need to have Tweaks installed on your TouchPad to toggle this new feature. Once you have both of them installed, you just need to go to the "Gestures" section of Tweaks and toggle "SHOW TAP RIPPLE" to NO to turn off the tap ripple.
