Hi,
I am new on TouchGFX and UI making, i have make many screens with transition in between i want to add a qr Code,
But when I just add a default qrcode no edit, but it dont show any thing, on that screen but when i change screen to different one and come back again the previous screen content print on qr code area.
First screen:
Qr screen: in the qr area the previous screen pixel shown
Qr next screen: when we go to next screen and again come back it again shows same issue.
or if we set the qr screen as startup it shows black completely in the qr region.
Kindly tell which issue causing this, as i does following troubleshoot from my sie;
1- use the invalidate in constructor, setup screen of view, and with screen coding in view file.
2- try to look every possible options like change qr versions, scale, ECC. mostly every option
3- try https://www.qrcode.com/en/about/version.html qr version table combitions to correctly check
4- change screens and try on different projects.
screen 1: w:230 and h:303
screen 2: w:320 and h:240
both are monochrome lcds
Also try in both touchgfx desiners 4.25 and 4.26
