Re: The MiniGL thread

@ddni, amig_os

No luck to get a video from any of you showing the bug with moving around a bit ?

Daniel think it can be very well z-buffers issues, and that they may be cause also by the fact that new minigl builded with different optimisation flags which may have impact on the floats which can cause in end z-fighting issues. So, i build 2 version of latest mgl source code

One is just the same as Daniel do, just instead of gcc 5.4.0, its 8.2.0, there is:

And another one, as Daniel ask is version builded without any optimisation flags, just pure -O2 (also builded via 8.2.0 on my side), there is:

http://kas1e.mikendezign.com/aos4/minigl/mgl_gcc820_opt2.zip

Plz give them a go (carefull, to be sure you not mess it up when testing, all after reboots, checking size of libs after reboot to be sure its correct one, etc).

But also in any case if one of you will made a video of bug, it will be easy to understand if it z-fighting issue or not.

@Daniel

At least with RCTW and Neverball z-fighting, pure -O2 build change nothing. But in case with those 2, issues was there and with 2.20 as well.
