GPUParticles2D's speed scale with scale curve cause texture flickering #58675

Open girng opened 2 years ago

Godot version

62765fb

System information

W10, RX 480, Vulkan

Issue description

If you set the speed scale property to a low value, and you use a scale curve, you'll see a white texture flicking across the the GPUParticles2D render area.

If you have a low speed scale value, and remove the scale curve, it removes the flickering though. It seems whenever a low speed scale property is working in unison with a scale curve, it creates the flickering

@girng The minimal reproduction project didn't upload (likely because you clicked away from the text field while it was still uploading). Try editing your post and upload it again.
