Thanks for logging thin, I'll have a look into it.

Do you use Wayland or X11?

Hi!

X11

✦ ❯ loginctl
SESSION UID USER SEAT TTY

1 sessions listed.

✦ ❯ loginctl show-session 2 -p Type
Type=x11

✦ ❯ lsb_release -a

Hi!

I found that with the combination of values for the variables below the application works!

✦ ❯ printenv | grep QT
QT_ACCESSIBILITY=1
QT_IM_MODULE=ibus
QT_AUTO_SCREEN_SCALE_FACTOR=1
QT_SCALE_FACTOR=1.5

However, the aspect seems a little big in relation to the fonts and other windows as you can see below!
And the movement of the mouse in the capture region becomes slower!

Hi!

I found the best values!
If you have more than one monitor, you can put the factors separated by ';' (exampĺe QT_SCREEN_SCALE_FACTORS="1.5;2")

env | grep QT
QT_ACCESSIBILITY=1
QT_SCREEN_SCALE_FACTORS=1.5
QT_IM_MODULE=ibus
QT_AUTO_SCREEN_SCALE_FACTOR=1

You can see that the screens look better!

Tested in my Ubuntu 20.04 VM and the only issue that I see is that icons and text is not properly scalled but the rest seem to be correct:

Is this the issue you're seeing? The Screenshot seems to be correct. That's now WQHD with 200% scaling.

Just tested with a fresh install of Ubuntu 20.10 and see there the same behavior, icons with fixed size are not correctly scaled but screenshots seem to be captured correctly as far as I can tell.

I have address the incorrectly scaled UI elements here #549, those should be fixed now in latest version, thought the CI might need some time to build it.

Regarding the screenshot issue you're facing, I might need more input from you on how to reproduce it. Best would be if you could try to reproduce it on a fresh installed VM @mrmodolo .
