Windows parametric masking performance issues

Software darktable
1

While testing darktable today I noticed when using parametric masks the sliders to adjust these masks to the targeted luma ranges get really laggy to the point where they don’t move but snap to where my mouse was after I release the mouse button.

This makes it really difficult for me to fine tune the ranges.

dt 3.0.2, OpenCL enabled. Windows 10. i7 processor 32 gb ram,. GPU Quadro P1000 4gb vram 10 bit not enabled.

Currently at work so cannot test more till tomorrow. Available to answer any questions however.

Try disabling OpenCL and see if that makes a difference.

Just ran a quick test after getting home from work. OpenCL off makes no difference still the same behavior. Turning OpenCL back on and to Very Fast for GPU instead of default also makes no difference.
