@andrew: if I bypass jit.gl.slab there are no trails on videoplane, but no glitches also; like a kind of mirror. I’m curious how to control amount of those trails – there is no erase_color anywhere in the slab, and changing ‘color’ attr (alpha ch.) in videoplane or slab just makes whole texture paler (and in extreme case – just white). So this empty slab isn’t just for security. So how it works? Below 3 screenshots illustrating my inquiry. (all other camera-videplane have slab bypassed).
1. without slab, vp color 1 1 1 1
2. with slab, vp color 1 1 1 1
3. with slab, vp color 1 1 1 0.5
