Print and print preview bugs

[socky]

Hi
I moved from 5.47.0 to 6.1.5 and I have printing problem of timetables and advanced statistics.
Print preview looks OK... but when I zoom in and move around the picture is distorted.
When I print the fonts looks bad and unreadable. I printed to pdf and normal printer, both looks bad.
I tested on two different computers, same result. Win 10 x64 Polish.

It might be a Qt bug. I will ask Volker to look at this topic, it is his part. Meanwhile, you might want to try FET-6.1.5-32bit from Volker's site, it uses an older Qt (I think 5.12 or 5.15). (FET-6.1.5 precompiled by me for Windows 64bit uses Qt 6.1.2.)

Thx for fast reply, confirmed that 32-bit version is working OK.

You are welcome!

Qt 6 changed the rendering plattform.
So i guess a bug of Qt 6 and/or the rendering api or your grafic driver.

Maybe there is an option to change the rendering device?

Hi again ;-)
After some testing I have narrowed problem to Windows scaling. In the beginning I tested FET on two different computers but both had 1440p monitors and 150% DPI scaling enebled. When I set scaling to 100% there isn't any screen issues. Also printing is looking as it should. So for now the solution for me is to disable dpi scaling for FET.
