Tone EQ cursor lagging on current Windows nightly

[sg456]

Describe the bug

When the tone EQ module is open and active, the cursor (the tone eq 'picker') becomes slow and jerky while over the image, but only when the image preview is smaller than 'fit screen'. For example when the color assessment mode is active, or when the preview size is set to 'small' in the dropdown list.

Not sure what kind of log would be relevant.

Steps to reproduce

Open a raw image (.nef).
Enable tone eq.
enable ISO 12646 color assessment mode
move cursor over image area.
cursor becomes slow and laggy.

Problem solved... I only discovered in writing the issue that my Nvidia driver was out of date. Updated, restarted, and kernels deleted, problem seems to be solved. Sorry about the noise!
