Cannot remember window position and size

[tkp206093]

Using Win11 23H2 3840X2160 150%

every time open spek is so small and In the upper left corner

I have added a feature to write widthXheight into config file
https://github.com/Safari77/spek
However, something in spek reduces width by 90 pixels, and height by 99 and then 138 pixels after starting. If someone knows how to fix that, it would be nice.
