That means the patch > series does not provide a general fix for that issue. Not sure how to reproduce the jumping on pen-up. I was able to draw circles, sign my name and actually today I wrote up the whole English alphabet on the screen. Picture here. https://drive.google.com/file/d/0ByWLwvGx8MeyVF9CTlhHU0FHMFk/view?usp=sharing Is there any particular pattern you want me to test with? I would still like to test with a more recent kernel on LCD7 cape. So, if anyone has ideas (other than I porting the LCD7 support) please let me know. Thanks, Sekhar
