PB 5.0 b6 Crash at re-open fullscreen

[kenmo]

Beta 6 is a great improvement, I can now run my game in fullscreen (at 60 FPS too)!

But I still have screen problems: now I get a crash (either IMA or "quit unexpectedly") when reopening a fullscreen (for example, to change to a new resolution).

OSX 10.7

Example:

Code: Select all

InitSprite()

; Open screen, draw red then green then blue
For color = 0 To 2
  If (OpenScreen(640, 480, 32, ""))
    ClearScreen($FF << (color*8))
    FlipBuffers()
    Delay(2000)
    CloseScreen()
    Delay(2000)
  EndIf
  Delay(2000)
Next color

EDIT: If it helps, I saw this error once or twice on CloseScreen():

Code: Select all

[ERROR] -{__NSMallocBlock__ __getValue:forKey:]: unrecognized selector sent to instance 0x2167fd0

Unfortunately, i can't reproduce it on my mac (10.6 and 10.. Could you try this debug lib and give me the output ?

www.purebasic.com/beta/macosx_x86/Screen

[kenmo]

With that library, I get the same result. The first OpenScreen / ClearScreen / CloseScreen seems to work OK, but then it hangs on the next OpenScreen, and quits unexpectedly after a few seconds.

Was it supposed to print a debug report somewhere? What output did you want?

[Fred]

You have to launch the created exe from the terminal.

OK, compiled the code posted above, first run:

Second run, from the same console, I didn't change anything:

You should have another log in it, have you overwritten the lib and relaunched PB ?

[kenmo]

Yes, and I just re-downloaded and re-started to be sure. Same results as above...

I'm supposed to look at just the terminal output, right? Not any saved log file or anything else?

Are you sure the lib at that URL above is the updated one? (81,245 bytes)

[Fred]

I will re-up it for to be sure.

[Fred]

Could you retry please ?

[kenmo]

Tried it again with the debug lib (now 57 kB), here are 4 tries:

Here's an update on this issue:

The good news:
- I've tested this on a few more Macs now, and none of them crash (only the Mac I'm developing on, of course )
- I'm going to release my game soon -- if other people have crashes then I will try to release a v1.1 fix later
- closing and re-opening a fullscreen is not something that happens very often anyway
- this might be important, or maybe it is totally unrelated: the crash seems to only happen when using an HDMI cable + television as my display (I don't know if this affects PureBasic at all... but other games run full-screen fine)

The bad news:
- it still happens in PB 5.0 Final
- sometimes it crashes on the second OpenScreen() and sometimes it crashes on the first CloseScreen() (maybe CloseScreen corrupts something which later causes OpenScreen to crash?)

[Fred]

Did you had users return about that ?
