Unknown CSI codes

[Luxed]

Hello,

When doing some commands under Neovim (0.3.1) while using Butterfly (3.2.3) I get the error: Unknown CSI code: t (116) or even Unknown CSI code: q (113).
When this happens, nothing gets written on the line:

To reproduce the error, the following command can be used (it also shows the information that should have been printed out by the :messages command on Neovim):

This has been tried on the latest version of Opera, Chrome and Firefox.

Ok you can safely ignore those errors.
CSI t category represents:

Window manipulation (from dtterm, as well as extensions by
xterm).  These controls may be disabled using the allowWin-
dowOps resource.
xterm uses Extended Window Manager Hints (EWMH) to maximize
the window.  Some window managers have incomplete support for
EWMH.  For instance, fvwm, flwm and quartz-wm advertise sup-
port for maximizing windows horizontally or vertically, but in
fact equate those to the maximize operation.

First CSI is CSI 22;0;0 t which means: Save xterm icon and window title on stack.
Second is CSI 8;73;111 t : Resize the text area to given height and width in characters. Omitted parameters reuse the current height or width. Zero parameters use the display's height or width.
Third is CSI 2 t : Iconify window

CSI q category is
Load LEDs (DECLL), VT100.
Last is CSI 2 q : Light Caps Lock.

So nothing important nor implementable in a browser.

Ok, that's good to know, but I still cannot see the text that I should in Neovim:
At the bottom left of the first screenshot, above Press ENTER or type command to continue, the text present on the second screenshot (the series of test lines) should be present. Also, the white line should be the status line.

I see no visual differences here between butterfly on chrome and xterm, could you provide a step by step reproduction guide?
