I’m writing an app in Jetpack Compose desktop, and I want it to open at a certain size. Similar to the –geometry argument for xterm.
Using the parameters to the Window() composable changes the size, but causes some flickering in Linux.
I haven’t found anything that suggests that such a parameter exists, but I thought I would ask here before I go through the painful procedure of building the libraries myself from source.

Note that for Windows, it seems to work fine to use the Window() parameters, but in Linux, the window is initially created with the size 800×600 and then changed to whatever I specify in Window().

Alternatively – is there a way to force apps to open in a certain size in Xorg?
