Chromium >=94 window move_frame gets wrong position

MyPhyja · Post by **MyPhyja** » Thu Oct 21, 2021 11:21 pm

I think this is a bug, but I'm not sure what it's a bug in. Is it a Chromium bug, a Cinnamon bug, or something else? Any help narrowing down where the problem is is greatly appreciated.

For context, I noticed this because the gTile extension started tiling my Chromium windows incorrectly.

It started in Chromium 94, and I tried the beta channel of Chrome 95 and this issue exists there as well.

Here's how to reproduce it:

Open Chromium and go to Settings -> Appearance and make sure "Use system title bar and borders" is turned off
Make sure the Chromium window is not maximized
Open Melange (Super+L)
Go to the "Windows" tab in Melange and see what window Chromium is (e.g. mine right now is w(28))
In the evaluate box in Melange, enter w(28).move_frame(true, 0, 0) (replacing w(28) with your window)

After doing this you'll see that the Chromium window does not actually move to the top left like it should using (0, 0). There's a space above and to the left. The window seems to be 8 pixels too low and 15 pixels too far to the right.

I tried reproducing this in Ubuntu (using Looking Glass instead of Melange), but the problem did not happen there.

This happens on both my desktop and laptop computers, but the specs below are for my desktop. I'm running Linux Mint 20.2 64-bit Cinnamon. Here's the detailed info:
