Hi,

any idea how to get Lecture Notes -app working under cromi-x? It's a notes taking app that allows you to draw on screen. I can see the line get's drawn while I move my finger on screen, but when I raise my finger the line disappears.

I believe the app writes to some display buffer while I draw, and when I raise the finger it writes the drawing into some other display memory buffer. Now this other buffer does not get drawn to screen. It is likely some chromi-x optimization that breaks this now. Any idea which, and how to get this working again? I recall it asked something about screen optimization while installing chromi-x, but how to disable that now that it's installed?

There is free trial version of Lecture Notes if any of you are kind enough to check this.

BR,

I have the paid version and it works fine under CROMi-X 5.4 and _that's V8 kernel. Not using rom2sd or data2sd, just "stock" flash install.

Nope, only the lecture notes so far. I also have the kernel that came with the cromi-x 5.3. I will try the upgrade once I get it downloaded. I'm on travel, and the download just doesn't succeed now. Tomorrow...

Finally at home and I got the latest 5.4 cromi-x rom downloaded. I installed it with dpi 213 selected. I didn't select the force use of GPU -option. Still the same, the lecture notes drawing doesn't appear.

I know the app draws, since I see the lines momentarily if I select an area to be cut. But then the drawing disappears again. I have cleaned the temp files and data from lecture notes. No help.

Any ideas?

I use the 240 DPI option - one possible difference.

Oops, I take it back, it works now! I had left the "force GPU rendering" on afterall during my last nights debugs. That removed ot works now with the latest 5.4 version. Yay \o/
