I can't reproduce this here. Could you please make sure you're on the very latest commit and try again. The win32 gui for flow is still very new and in active development.

@neurocyte
Thanks for kindly reply. I double checked source version is latest.
The result is same. I am on windows 10.

d:\other\project\flow>git rev-parse HEAD

And if you resize the window corrects itself?

[pebble2050]

When windows is resized, the result is more complicated.
Sometimes ok ,sometimes selection cause rand text copy(eg. display text from above or right)

@pebble2050 can you attach your hello.py file? I'm wondering if there is some sort of BOM or something special about it that could be causing the issue.

[marler8997]

Also @pebble2050 what's your zig build command you're using, and what's your host machine? Maybe you could send the output of systeminfo...I'm concerned about those weird characters in your window title.

@marler8997
I am using zig build -Doptimize=ReleaseFast to build
since github not allow to upload .py file, I change hello.py to hello.txt
hello.txt

[pebble2050]

I tried zig build -Doptimize=ReleaseSafe, the result is same.
The weird characters maybe because my windows 10 system language is Japanese.
This two bug seems somehow related.
The first line is not rendered maybe because line height is not correct calculated(eg. calculated from line 2?)

[marler8997]

You need to provide -Dgui to zig build in order to build the GUI version.
Also, the exe itself has been renamed to flow-gui.exe, so maybe you are just running an old version and not realizing it?

@pebble2050 it's now possible to configure the fontface and fontsize in the latest master commit. You might want to try configuring different fonts and see if your issue is perhaps related to a specific font.
