Here the minimum code:

@REQUIRE "rebelsdl"

BeginDoubleBuffer(True)


Circle(100, 100, 200, ARGB(128, $aaaaaa))
Flip()
WaitRightMouse()

Hollywood 9.1 Windows 10

Two problems with this.

1. It crashes
2. It doesnt show any error.

Is this supposed to be so? I understood that when using the Circle command on RebelSDL it would revert to using Hollywoods own drawing instead of RebelSDL, since RebelSDL doesnt support drawing a circle.

Also, this only happens when trying to draw alpha circle. If I use instead of "ARGB(128, $aaaaaa)" - "#WHITE" as example, it will work fine, so seems to be alpha channel usage the issue.

Nope, this is clearly a bug. Will be fixed.

Just noticed this same problem is with GLGalore as well.

Just using DoubleBuffer without @REQUIRE for RebelSDL or GLGalore, however, works right in Windows.

Yes, that's no surprise because it uses the same plugin interface as RebelSDL.
