I have my bigger sample code on Debian and when I try run it on Windows I found problem with displaying lines under thickness 0,5. What can cause it?

Could you attach two screenshots showing the output on Debian and Windows?
Sorry this is not Cairo problem it is in app, but is difficult that in Debian is all OK but in Windows not. I need more time to analyse, I made test with hard writen lines in on_draw metod and it is OK on both systems:
