Hi Stuart

The 4x20 lcd does not distort or corrupt on my system.
BUT as you say, you are printing the "Data Received" at 1,0 and it is actually at 2,0 (X,Y).

Hi John,

Hi. Looking at the screenshot I think you may have a space before the 'D' of "Data". I hope thats it anyway, one more thing to tick off!

Sorry guys I didn't put it in there intentionally, but the distortion on the LCD wasn't my fault :oops:

Jonny did you see the first pic because that was before I even put any data on the LCD

cheers

Hi Acestu.

No problems, not the worst of mistakes! Yeah, the problem is the LCD screen is suffering from Z-fighting. I made a modified component for this and post it online here:
http://www.matrixmultimedia.com/mmforum ... 640#p50704

I assumed this had got into the latest release but as my OpenGL version does not show this problem maybe not. I can double check this when back at the office tomorrow.

The other option is ensure Object Shadows are disabled if this may be causing problems. If that is the issue (we have only seen it once on an OpenGL 1.1 version, and it should be fixed in the next release), ensure that shadows are tabletop or off, save your project then restart Flowcode, as the bug makes a real mess of FC when it kicks in).

Jonny
