HiDPI Support in Linux

[salukibob]

Hello,

I've recently purchased a new laptop with a HiDPI display (3840x2160). I have installed a copy of Elementary OS (Ubuntu and based on Gnome 3). It scales the display perfectly straight from installation.

I then purchased Aftershot Pro 3 and was excited to get started editing, but was very sad to see that Aftershot Pro doesn't properly scale and displays very small (see attached screenshot). I'm rather surprised that a high end product like ASP3 wouldn't have tested this and I'm pretty disappointed.

When I start the program from the command-line, I noticed that ASP3 uses some elements of the QT libraries, so I tried setting the QT_AUTO_SCREEN_SCALE_FACTOR by invoking ASP3 as:
$ QT_AUTO_SCREEN_SCALE_FACTOR=1 AfterShot3X64

But that didn't work either. Does anyone have any other suggestions before I admit defeat and change my display to 1920x1080 (and feel mighty saddened by it all)

Thanks for any help
Rob

Hi,

I found this in different post

[...]
The underlying framework QT supports setting pixel per ratio to make aftershot a little more usable on hidpi screens.

Start aftershot with and many elements will appear bigger.
export QT_DEVICE_PIXEL_RATIO=2;AfterShot3X64

Menu fonts are still small though.

Brilliant! Thank you, that works great. Interestingly that environment variable is listed separately from the others for DPI scaling in the QT docs.

Now ASP is back to being great again! Thank you.
