Alright, I'm just getting more and more confused. I've done
a lot of testing with the RC1 build (SDL 2.0.5, "their"
build script) I posted earlier. It crashes always/often
(unsure if it's been exactly 100% or very close to it) in
Closure at the start of the multi scroller screen - in ST
mode. It does not seem to crash in STE mode. The code paths
in the demo are extremely similar (sync scroll used also for
STE) so already there it's pretty strange.
I have not been able to provoke a crash with anything else
I've tested (mostly Union Demo and We Were @) - at all.
I'm out of ideas. It seems to be an SDL2 issue - but caused
somehow by the specific behaviour of Closure in ST mode. An
also only on older versions of macOS ... so I can't really
see this being a showstopper. But I would appreciate it if
others test as well.
Btw Nicolas, the big y-swinging SYNC disting logo in the
beginning of Closure shows two non-fullscreen lines at the
bottom of the screen. I'm very surprised that I would've
made such an error - is it possible Hatari is displaying 276
lines even though the VBLANK at line 274 should've kicked
in? Needless to say, I don't see such non-fullscreen lines
with my original Closure-disc on my STE with my Dell 2001FP
with vpos set to show all (AFAIK) lines ... :P
