Hi MM,
I Have an LCD module on the dashboard set to 4 x 20, when putting the dashboard at the bottom off the screen, when I pull it back up all the LED screen is
messed up , I got a screen grab of it, below,
Edit: I have closed the panel and opened it again and the LCD is the same as the pic
Thanks
Acestu

Hi Stuart
Can you post you flowchart?
Just tried adding a 4x20 and moving it about, but no problems here

Hi John,
Is it me or is the LCD printing in the wrong place too,
Surely this shoud be Cursor 2,0

This is the chart I am using:
EDIT: This chart was not made from scratch, I was altering Benj's Visi-demo chart
System, Win XP Pro SP3 32 bit Core 2 Duo

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,
Yes the guys at MM should be in tomorrow after the bank holiday so we will see what they think of it, I will try and reproduce the fault in the meantime...
cheers

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
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:

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).
