I am experiencing a weird issue while rendering. It started randomly two or three days ago and is now affecting any file that I work in, basic or complex. When I start a render, everything will progress as normal until I change the tone mapping option to logarithmic. Immediately the cycle count and render time will stop updating and the render will appear to be frozen. I found that if I wait long enough, the render is actually working in the background and will eventually show as complete. When the render appears frozen, if I click on the menu bar and jiggle the render window, the count will continue to progress, but will freeze again if I click off the window.
What’s giving me the biggest headache, though, is that if I attempt to change the exposure, bias, or contrast setting with tone mapping set to logarithmic, Rhino will actually freeze and become unresponsive. This happens if I attempt to adjust these setting during a render and if I wait until after the render has finished. I’ve waited ~20 minutes with a frozen program on a couple occasions hoping it would wake up, but once its frozen, I am forced to close Rhino with task manager. If I have another model open in a different window, though, that window is unaffected.
Some other strange behavior: under the histogram panel, the color bars next to “before” and “after” will continuously flash big and small and the window seems to lag severely when I either I move the render window or mouse over menu buttons.
I’m working on a Thinkpad P1 Gen 5, i9-12900H, 64GB RAM, RTX A5500. I recently updated all my drivers and updated Rhino yesterday. I’ve attempted both restarting my computer after a freeze as well as a full shut down but the problem persists.

Rhino plugins that do not ship with Rhino

I’m not one of the experts (@John_Brock@wim ), but from what I’ve seen on this forum one of the usual first steps is to disable any plugins that don’t ship with Rhino and see if the problem goes away.
Do you have a file you can share that shows this behavior? I can’t repeat that behavior here. I have the same plugins installed, so those cannot be the cause of the issues.
