FW Annex32 WiFi 1.41 beta 5
I tested with M5 fire, but I guess it concerns all models.
Code: [Local Link Removed for Guests]
gui.init 20, black 'reserve memory for 20 GUI objects. clears screen to black
txt = GUI.Textline(10,50,190,20, "Text Line Here", 2) 'x,y,w,h,text,fontsize
but = GUI.Button(20, 200, 100, 20, "BUTTON!",2 ) 'x,y,w,h,text,fontsize

Hi Kabron
Tested with version 1.43.5 and black screen result.
Now tested with the entire example from my manual and works perfectly.
I don't have a touch screen on my M5stack black.
If I make the choice in Config Options M5stack then an inverted screen and with M5stack #2 a normal screen.
' simple GUI example.
gui.init 20, black ' spare memory for 20 GUI objects makes the screen black.
txt = GUI.Textline(10, 50, 190, 20, "Text Line Here", 2) ' x, y, w, h, text, fontsize.
but = GUI.Button(20, 200, 100, 20, "BUTTON!", 2) ' x, y, w, h, text, fontsize.
gui.setevent but, TOUCH, buttonclick ' set touched event, jump to buttonclick.
interrupt 39, buttonclick ' if using M5stack can't click screen, so use the left button.
gui.autorefresh 30, 1' gui items automatically every 30ms including touch.
wait
button click:
gui.settext txt, "Button Pressed" ' change line of text.
return

I have been testing dynamic layouts on different TFT screens and sizes - including M5stack - and it seems that the Annex Config setting is absolute whereas the TFT.init setting is relative to the Config setting.
So in practice I found the display orientation can be changed simply by using an appropriate TFT.ini setting at the top of the script, as in this snippet:
Code: [Local Link Removed for Guests]
M5stack=2 '0 for touch buttons only, 1 for M5stack hardware buttons only, 2 for both
'touch.calib: reboot 'uncomment to run once and re-calibrate after changing screen orientation
Xres=320: Yres=240 'TFT screen size
'Xres=480: Yres=320 'TFT screen size for 4"
orientation=1 '0=Portrait, 1=Landscape, 2=Portrait reversed, 3=Landscape reversed
background=blue
tft.init orientation
gui.init 25, background
Not all of the variables are necessary for orientation, for instance the M5stack value is just used as a flag to enable/disable GUI touchbuttons and or hardware buttons.
GUI objects depend on the existing TFT configuration, so may require an appropriate TFT.init added at top of script to set the required orientation
(and any orientation change should be followed by touchscreen calibration, of course).

HI all,
just to clarify :
- The display model must be selected in the config page and cannot be changes
- The orientation is set in the config page BUT can be also changed in the code
