hello,
just finishing update 3.19 (applied on a 3.18) using a CR-RW, not apparent problem ...
...until i simply :
-go to the Ambient Menu (top left),
-select 'A propos de MorphOS' (french menu, "About Morphos") that displays as expected the dev credits, my name as owner of a MorphOS licence,
- then i click on "OK" and as the page closes, the display starts doing some interlacing stuff (with content blinking) and i cannot even manage to reboot by the menu the machine, as i cannot reach the reboot option location with that strange display.

Note that when booted with ISO (from CD or DVD), leaving the about menu is fine (except there is no user licence info displayed, normal).

Has any one else encounter/tried this ?
i re install from a second burn (DVD RW) ISO and still get the same result on this powerBook G4 1.5 GHZ that runs fine in previous version....

Thanks.

I take a screen picture, here is a link to it :

P.S. : my second setup is a powerbook G4 1.67 GHZ, i'll wait before trying updating from 3.18 to 3.19....

This could be a 5.4 (15"), a 5.5 (17") with ADB based KBD and trackpad, or even the BTO downgrade 5.6.

I'd expect most developers and betatesters to use 5.8/5.9 models with some 5.6/5.7 sprinkled in, so it might be an oversight based on the slightly different HW. Failing HW like a dying HD could also be an issue.

>powerbook G4 1.67 GHZ
Which could be anything from 5.6 to 5.9.

I have similar problems in my powerbook from time to time. Dont know if it is a powerbook problem or what.
I reset the machine and all goes ok.
That happends with previous versions too.

@tolkien

Are you talking about the screen being garbled at boot up, or does it really get triggered while using?

Thanks for your replies.

MY first Powerbook (1.5 ghz) is the 15 inch one (with radeon in it, the only that Morphos manages).

Th problem is reproductible (following steps : about morphos, click OK to quit that page) and the display problem appears immediately, whereas no problem at all if I use Morphos for other tasks (game, browsing).

I will check on my second powerbook (latest 1.67 ghz G4 release with hd screen and ddr2 ram) the same steps before applying the upgrade, just to have fair comparison, on two different hardwares.

These hardwares are getting older, of course, but usually we get time to time some random artifacts, not so reproductibles ones.

>MY first Powerbook (1.5 ghz) is the 15 inch one

So either a 5.4 or the downgraded 5.6.

Both have the same GPU and screen, but differ in other parts.

Effectively, from Monitor System in Morphos, it displayed 'Machine : PowerBook5,6'

I'm experiencing this issue from time to time, too. After a reboot the display is normal again. Powerbook 5,6 1,67 GHz with BTO 128 MByte VRAM.

so i've just updated my second PowerBook G4 (model 5.8) and before/after upgrade to morphos 3.19 it does not show the scrambled screen i experience on the older model when looking to credit / licence infos page and clicking on ok.

So it seems limited to that Powerbook 5.6 model, maybe i could try a fresh install... but it is not really blocking, i'll stay for the moment as it is.

i start to understand from where the problem comes from :
i sometimes use the external display (2nd screen) and for that have a second display definition in MUI (higher definition than the LCD of the laptop) :
- booting the poweBook5.6 with connected 2nd screen leads to display Morphos only on 2nd screen (not on laptop)... but then the described issue of strange display once displayed the credits/licence is gone.

Is it possible some windows have a preferred display to show up (or remember last used one ?).

Still digging that
