Tdrop window move down a distance of window title on every "hide & show" execution when "-r" flag is used

[eval-exec]

I bind a custom shortcut to emacs by tdrop -r emacs
when I first run tdrop -r emacs, the emacs window appears here:

Then I run tdrop -r emacs to hide the emacs window, then run tdrop -r emacs to show the emacs window, it appears in here:

repeat last 2 steps, it appears here:

It seems that when I hide and show the window by tdrop -r emacs, the window would move down a distance of window title.

some infomations may help to solve this issue

This sounds like it could have to do with the window decoration or -S. Does adding the -S flag help? If not, you'll have to find the correct value for --decoration-fix.

I'm getting this on Plasma/Breeze with Alacritty. Neither of those flags seemed to make a difference. If I disable the title bar for Alacritty in Plasma settings, things work as intended, so you're right that it's an interaction with the window decoration.

Works as intended no matter what:
tdrop -maA -w 100% -h 48% -s dropdown alacritty

Works as intended, but the top of the window is actually a pixel or two lower than the top edge, with or without decorations:
tdrop -maA -w -0 -h -500 -s dropdown alacritty

Works as reported with decorations, as intended without (this is what I've been trying to use):
tdrop -maAr -s dropdown alacritty
