Might be specific to Windows. I wonder if it’s only me…
To try to reproduce, start with no corrections, make some mask (tested with Control Point, Hue, and AI masks), set LA Clearview to 100 or 50 and then use some Selective Tones slider (Midtones and Shadows tested) to quickly change the setting, either by dragging the slider with a mouse or using mouse scroll wheel. After few tries, you may get the masked area too dark or too bright. The exports look OK, as expected. Selecting another image and going back fixes the display until next occurence. I’m not sure if Clearview setting is important here, or it just makes the problem happen more often.
My setup:
Win11pro 25H2 (26200.8246), RTX4070 (tested 595.79 and 596.36), i7-14700KF (no iGPU), 32GB RAM, 4K monitor @60Hz.
PL9.7, both ‘Viewer quality’ options enabled in Preferences → Display, ‘Windows ML Acceleration’ set to ‘Maximum performance’ (didn’t try the other setting yet), ‘NVIDIA GeForce RTX 4070 [via NvTensorRTRTXExecutionProvider v1.23.2]’ chosen, as seen in PhotoLab log. Windows Update shows the following NVIDIA TensorRT RTX execution providers installed: KB5089168 (installed automatically on 29 Apr, some time after update to PL9.7), KB5083460 (installed by PL9.7?), KB5079257 (by PL9.6?).
Here are some examples of a clear sky photo (dust spots check done in the field) with a Loupe tool used solely to demonstrate the problem – I don’t have to use the Loupe to see the problem, if it happens. Sometimes Loupe displays the right correction and normal display is “wrong”, sometimes it’s the other way around.
