LineART problem with Colour Blend Parameters

Hi all,
I am the user of Calamus SLC 2015 and I Have some strange problem with this module when I open this icon "Colour Blend Parameters".
On the begining my system is Hades with ATI MACH 64 or Atari TT with ATI MACH 64 (ISA card).
On Hades it works in 32bits or on TT 256 colour resolution. When I create any vector object and open window "Color Blend Parameters", filling in the preview window is very slow, line by line in the case of Atari TT, Hades is completely falling apart, there are wrong horizontal lines all over the screen. Accordingly, it can not be called completely because it practically becomes useless.
What is interesting if I switch and start computers in mono mode (two colours), this problem does not exist

Is this the fault of the graphics driver, can it be changed somehow?

For comparison, I can this function works properly on Atari Falcon 060 with Radeon graphics card.
Can anyone check it even in the case of TT?

As it looks, I can send pictures to the private.
Regards
Kroll

I guess this issue is due to the graphics mode. LineArt hasn't been adjusted for HighColor or 256c modes, but should be used in TrueColor mode.

Nevertheless, I'd recommend using the Multicolor Blend module which creates pixel graphics and can even add distortion and more then just three colors to a color blend. Furthermore, these raster images will be output properly into PDF by Bridge, while LineArt vector blends cannot be output into PDF by Bridge.
