Cell size calculation not settled on startup

[hzeller]

Describe the bug

When first starting the terminal, the cells occcupy a particular size, as calculated from the number of columns and rows and pixel width/height from the screen ( TIOCGWINSZ). That size seems to be wrong/not settled yet. After a resize or reloading of the wezterm.lua, the correct font size is calculated.

This is maybe related to #535 ?

Environment (please complete the following information):

• OS: Linux X11
• Version: 20210314-114017-04b7cedd-16-ge5ae1d47

To Reproduce

With font config below, start terminal and query size.

Current timg has a new --verbose that can be helpful.

Right after start-up, run a timg:

timg --verbose someimage.png
... (image, somewhat distorted as the scale factor is calculated by timg)
Terminal cells: 80x24  cell-pixels: 8x16

Now, force recalculation, either by resizing terminal or touching the configuration file

timg --verbose someimage.png
... (image, this time properly scaled)
Terminal cells: 80x24  cell-pixels: 10x22

Configuration

Relevant font configuration

   font_rules = {
      {
	 intensity = "Bold",
	 font = wezterm.font("Terminus (TTF)"),
      },
      {
 	 font = wezterm.font("Terminus (TTF)"),
      }
   },

Expected behavior

Font size is correct on start-up (in this case: 10x22).

The font matched here is
TerminusTTF-4.46.0.ttf.gz

Another good catch! Yes, very similar to that other issue. Should be fixed now in main!

Confirmed fixed!
Thanks!
