CreateSprite stalls

[jamirokwai]

Hi there,

working with PB 6.02 ARM, C Backend on my MacBook M2. This code stalls at the CreateSprite()-function.

Code: Select all

InitSprite()
OpenScreen(1280, 800, 32, "bla")
msCurs = CreateSprite(#PB_Any, 64, 64)
Debug mscurs

Also with 5.73 on Intel iMac 27"

So it has nothing to do with C backend.

jamirokwai's example code indeed doesn't respond anymore after exexcution in the IDE on my iMac 2019 27'' with Intel i5-8500 processor on MacOS 13.5 'Ventura' and PB 6.02 with Asm and C backend. But his code has two shortcomings: it doesn't test the return value of InitSprite() and OpenScreen(). When running this code from PB's help for listing all supported screen resolutions on my Mac hardware, I had to find out that 1280x800 isn't supported:

Code: Select all

InitSprite()

If ExamineScreenModes()
  While NextScreenMode()
    Debug Str(ScreenModeWidth())+"x"+Str(ScreenModeHeight())+"x"+Str(ScreenModeDepth())+"@"+Str(ScreenModeRefreshRate())+"Hz"
  Wend
EndIf

When changing the screen resolution from 1280x800 (unsupported) to 1280x720 (supported), jamirokwai's example runs like a charm!

This modified example displays an error message if InitSprite() or OpenScreen() fails:

Code: Select all

If InitSprite() = 0
  MessageRequester("Error", "InitSprite() failed!")
Else
; If OpenScreen(1280, 800, 32, "bla") = 0 ; Not supported on my iMac 2019 27''!
  If OpenScreen(1280, 720, 32, "bla") = 0 ; Supported on my iMac 2019 27''
    MessageRequester("Error", "OpenScreen() failed!")
  Else
    msCurs = CreateSprite(#PB_Any, 64, 64)
    Debug mscurs
  EndIf
EndIf

Thanks for the info, shardik!

I found 1280x800x60 in the list you also provided the code for.
So, the bug/error lies in OpenScreen()?

Confirmed. This may be related to M1/M2 macs.

I changed the code for examining screen modes. After some flickering... See the table. X means, it works.
It's on my MacBook Pro M2.Working modes start with 1920x1200.

Don't know. Is this a bug? Not really...
Or do I really have to check all modes until I find the smallest one working

Code: Select all

InitSprite()
If ExamineScreenModes()
  While NextScreenMode()
    wide = ScreenModeWidth()
    high = ScreenModeHeight()
    If OpenScreen(wide, high, 32, "test") = 0
      Debug "-" + Str(wide)+"x"+Str(high)+"x"+Str(ScreenModeDepth())+"@"+Str(ScreenModeRefreshRate())+"Hz"
    Else
      Debug "x" + Str(wide)+"x"+Str(high)+"x"+Str(ScreenModeDepth())+"@"+Str(ScreenModeRefreshRate())+"Hz"
      CloseScreen()      
    EndIf
  Wend
EndIf

Got it. Seems to be tied to the actual retina resolution vs the scaled resolutions.
