Is there a way to increase the size of the interface

Having trouble with LMMS? Ask about it here.
Everything from the knobs to the text to the icons are so small that I have to sit very close to the monitor to make out what they say or do. After some time I just end up with a massive migraine. Is there a way to increase the size of the interface, or is there a theme someone could recommend?

If you have issues with the interfase on 4K+ screen, i think you have an outdated version. Current stable release is 1.2.2!
You need to read how to upgrade, and most important, where to get your supported lmms-installer from:

Let us know the outcome :)
Thank you for the response. I'm currently on version 1.2.2, but I did manage to figure out a solution after some searching. Running lmms with the following environment variables scales the interface up for me. This is on Linux so I have no idea if it would work with any other OS.

export QT_AUTO_SCREEN_SCALE_FACTOR=1
export QT_SCREEN_SCALE_FACTORS=1.5

I wasn't aware that QT programs could do this yesterday. Sorry for the trouble.

Oh, thank you very much! It helps a lot!
Now there is another things — anti aliased UI elements and some unscaled fots.
At QT_SCREEN_SCALE_FACTORS=2 icons and fonts looks great, but with less variable value become ugly. It is not a big problem, but still…
A quick search did not give me a good (easy and fast like this) answer how to disable that anti aliasing for all elements.
And there are still some fonts stay unscaled.

I have regular (old) display with standart dpi, but I want don't strain my eyes, and scaling is a great compromise between good vision and usability of the UI.
