A Blitzmax Medical Mystery - Paging Dr. Codemaster

I'm having an issue between debug mode and non-debug mode that is perplexing. Included is all source code, so you can try to replicate.

I'm using drawPoly for all of the drawing. The only class that *should* be relevant is the Trail and TrailSegment class, in Trail.bmx.

Debug Mode:



Non Debug Mode:



Blitzmax 1.28
Intel Mac OSX 10.5.2
Radeon X1900xt

Source:

Same results as above, although in the non-debug build I can press the right key a bunch and it looks fine, pressing the left key a bunch makes it worse. (no effect, other then the speed of the circle, on the debug build)

What's your setup Plash?

works fine here on G5 mac running 10.4 in both debug and release.

Inserting a "delay 40" befor flip makes it work here.
A "delay 39" let it appear corrupt again.

WinXP, Blide, Core2Duo, 8600 GTS

Same thing here - delay 40 makes is work, delay 39 does not. Pretty strange!

Windows XP, AMD 64b 2.21ghz, 2.5gb, ATI HD Radeon 2600 PRO.

Works fine on my MacBook, 10.5.2, Intel GMA

does this count as a bug?
