HiDPI font's are not following the Windows scaling

[pepemosca]

Hello,
I'm sorry in advance if this issue was covered before, but I was not able to find it.

I have a 4K display.
I have Windows 10 20H2.
I have Windows scaling set to 150%.



And XnView MP has a different scalling than the one I had set. Fonts looks bigger than my setup of 150%.



Any ideas how to fix it?
Thanks!

please start XnView with -noDpiScaling argument

[pepemosca]

Looks better, thanks.
Additional question, can I control the amount of scaling? So the icons don't look that small.
Thanks!

[xnview]

you can set environment var QT_SCALE_FACTOR

[pepemosca]

Can it be placed somewhere at the %appdata%\XnViewMP\xnview.ini or in the command line target?

[xnview]

no you need to add a environment variable

[chaotic.sys]

Thank you for a variable!
My case is exactly the same. Latest Win10x64, 150% scaling.
XnViewMP 0.96.5 - all good:

But 0.97, 0.97.1:

The DPI compatibility settings kept the font size just as huge.
Interestingly, the variable had to be set to 0.75 for the correct size.

The problem I'm having by changing the environment variable QT_SCALE_FACTOR, is also affecting other software that I use. For example https://rstudio.com/products/rstudio/download/.

Any other idea on how to re-scale XnView?

Thanks!

Hmm, I just noticed that my GoldenDict is skewed because of this variable. So I don't even know which of the two to choose : )

UPD The only working solution is to roll back to the old version.

you can use -noDpiScaling argument to start XnView

I tried it, it works : ) I usually launch XnView from Explorer by clicking on thumbnails. Not sure how to apply the argument in this case. Through the bat file - somehow not very good : )

Having same problem. XnViewMP starts starts with 200% scaling, instead of 150%.
-noDpiScaling switching scaling off entirely, making everything too small.

Can it be just reverted to previous scaling approach? It was working.

which font scaling value do you have in windows?

[regs]

150%

Reverted to 0.96.5 for the time being. That one is fine.

0.80.1 fix this issue
