Description:
I use a basic shape completely black with 25% transparency, when I add an animation to it (other than a basic appearance) the animation is bad, for my example, I use the fade animation. Otherwise when I launch my libreoffice with safe mode, the animation works very well.

Steps to Reproduce:
1. The background should preferably be dark blue.
2. Create a basic shape in black with 25% transparency, without line
3. Create an animation on the shape you just created, preferably a fade-in animation.
4. Start your slide.
5. Click once to fade the shape in.

Actual Results:
The shape is badly animated, a weird texture is created during the animation, and at the end of the animation, the weird texture disappears, making way for the shape.

Expected Results:
It shouldn't put that weird texture during animation


Reproducible: Always
