Tab items background strange behavior

steve64

I noticed (at least in LuaRT 1.9.5 and using theme=dark) the following strange behavior.
I create a Tab widget with 3 TabItem children.
When the app starts on the first time, the first TabItem is shown properly.
If I switch to any other panel, the dark background is not fully filled at the bottom of the Tab.
The are few pixel lines that do not have the proper color.
SInce then, also the first panel takes the wrong aspect.

Do you have a screenshot of this, I cannot reproduce it on my Windows 11 setup

I understood the root cause!
It happens when changing the font size of the tab headings.
See this example:

ui = require 'ui'
local WIN_WIDTH = 1018
local WIN_HEIGHT = 835
ui.theme = 'dark'
win = ui.Window('TEST CASE', 'single', WIN_WIDTH, WIN_HEIGHT)
tab = ui.Tab(win, { ' ONE ', ' TWO ', ' THREE ' }, 5, 5, 760+130, win.height-10)
--> tab.fontsize = 12
tab.fontstyle = {bold=true}
t1 = tab.items[1]    
t2 = tab.items[2]    
t3 = tab.items[3]
win:show()
repeat
  ui.update()
  sleep(1)
until not win.visible
