Widgets alignments collapse and text getting chopped off when scaling to 125%

On windows if system scaling has been increased to 125% GUI looks bad. Texts gets chopped off and widgets alignments goes bad too.
This is happening only when windows settings/scale factor is 125%. If it is made 100% or 150% or 175% it works good.
Attached example reproduces it
Steps:
increased scaling factor to 125 % and run this little example to see it.

Update:

This issue is also seen on 150 and 175% in some case. LIke If  HighDPI Scaling enabled  and setting 96Dpi is set. Then it is showing problem with 125% only otherwise issue can be seen.
