Xisco from where QR generator in 4.1?
Comment 5 Xisco Faulí 2019-10-16 14:16:57 UTC
No need to generate a QR code, use can use the file attached
Comment 6 Aron Budea 2019-11-16 22:18:52 UTC
Started in 4.2, but I can't start a lot of builds in that repo now, I get the following error message, and it quits:
javaldx: Could not find a Java Runtime Environment!
Warning: failed to read path from javaldx

All I can say, the exported PNG is already bad at this commit: 6c3a09b3b3ca9ad0c81a55efaaedad35c39de767

Example: www.qrcode-generator.ch 
/1.) Select text icon and enter text 
/2.) create qr code 
/3.) PNG and open with IrfanView 64-bit (downolad www.irfanview.com) 
/4.) Edit/copy 
/5.) insert in Libre-Office document
Comment 8 Buovjaga 2020-06-08 15:05:41 UTC
I am unable to open attachment 153742 [details] in the older commits of Linux 42max repo. However, going backwards from the commit mentioned by Áron, I can say that the bad result is already in source commit ed87e4c4b09d0f623c350528a4f6a6d049735bd1

I'm calling this notBibisectable.

This is not equivalent. With this, there is no problem in the latest commit of Linux 42max repo.
