Launcher window gets smaller and smaller each time opened

Launcher gets smaller and smaller each time you open it, and it is related to the "height" and "width" values that keep changing in .minecraft/window_settings_launcher.conf file. I have attached a screenshot to show what I mean. The window size is still the same, but the actual launcher canvas that gets drawn gets smaller and smaller - with the rest of the space being filled by the window behind it. Tried reinstalling the game and launcher, but that did not help.
