Do you perhaps have zooming enabled? (right click on Desktop > Display Preferences). 4k usually comes with a 250% zoom default in Windows. I have mine at 200% and Orange seems to work fine.

[hermandr]

I have set zooming to 100% and my desktop is really tiny but Orange is correct size.  Any other suggestion? Thank you for your time.

My Orange on 4k screen with Win looks ok, but I remember there being some issues on smaller screens. However, usually it was the opposite - the icons were too small.
Perhaps @acopar will know how to handle this?

I recall this issue on older Qt4 versions when combined with touchscreen or hidpi laptop screens. Recent versions of Qt have better support for hidpi:
http://doc.qt.io/qt-5/highdpi.html

Use orange miniconda installer and update to the latest pyqt version (which will also upgrade qt as a dependency):
C:\Program Files\Orange\Scripts\conda.bat install pyqt
or
C:\Program Files\Orange\Scripts\conda.bat update pyqt

@acopar this also happened on a Win 10 miniconda install (so with Qt5) that a guest had in the lab this week. So upgrading Qt would not help.

Hi, I have tried to update using Use orange miniconda installer and update to the latest pyqt version (which will also upgrade qt as a dependency): C:\Program Files\Orange\Scripts\conda.bat install pyqt or C:\Program Files\Orange\Scripts\conda.bat update pyqt the result is the same, no change.

Which scaling level do you have set? Qt5 does not handle non integer scale factors well QTBUG-65061, https://bugzilla.redhat.com/show_bug.cgi?id=1381828

Still the discrepancy looks too big.

Do you by any chance have QT_SCALE_FACTOR environment variable set?
You can check this by running

set

from the Command Prompt

Can you please also try running:

set QT_AUTO_SCREEN_SCALE_FACTOR=0
"C:\Program Files\Orange\python.exe" -m Orange.canvas --qt "-platform windows:dpiawareness=0"

(try also with ...dpiawareness=1 and ...dpiawareness=2)

[hermandr]

Thank you it works!

What fixed it?

[ajdapretnar]

@ales-erjavec Thank you so much for working on this and figuring it out! 🌟 This bug has been bothering several users.

[ajdapretnar]

I tried to set the scale factor on Linux Mint, but didn't work. I can try again and if it doesn't work, I can bring my laptop to work and we can check.

[lanzagar]

I think @robertcv has a similar problem on Ubuntu and he does not have a hidpi screen. Maybe @ajdapretnar and @robertcv can show the problem to @ales-erjavec and he might have some idea about what else to try.

BTW, is the current state of this issue fixed for windows with hidpi, and there are just similar problems on linux (even on non hidpi)?

[janezd]

@robertcv, @lanzagar, ping?

[lanzagar]

Well the title of this issue said windows and hidpi. I suggest we close this, and if @ajdapretnar or @robertcv can still reproduce the problem on ubuntu and/or non-hidpi, they should open a new issue and probably ask @ales-erjavec for help in solving it.
