Sliders are not presented when the screen size is small

[eyalk11]

Describe the bug
The range sliders are not displayed sometimes and sometimes they do.

That is really a matter of proper width and height . I am not sure..

To Reproduce
This is not minimal, I admit.

pip install --no-binary :all: git+https://github.com/eyalk11/compare-my-stocks
python -m compare_my_stocks 

Try on big screen , and on small, you wont.
Also, I tried resizing the window to smaller size(can't repaint), and increasing it and they disappeared.

Given the same code, on a 21' screen it worked , and on 14' it didn't.

Screenshots
Screenshots and GIFS are much appreciated when reporting visual bugs.

Desktop (please complete the following information):

• OS with version Windows 10

• Python version 3.9.6

thanks for the report @eyalk11. will try to have a look soon.
(note, the 6.2.1.1 bug is now fixed as of #51)

I corrected the sizes a bit and it doesn't happen anymore.
There are two other bugs in this screenshot. The handles' values are behind the form's labels. and the handles are not the right shape.

yes, proper scaling on windows has generally been difficult, it seems to vary from PC to PC, depending on screen scaling and resolution. it's not something I have particular expertise in, so welcome anyone who does to weigh in
