Following the latest update to Lightroom Classic 7.2 there seems to be a problem with the develop pane.
After workign for some minutes, at some point the picture will not change anymore and the module seems to be frozen. Pretty annyoing and only restart helps.
Cannot judge if the formerly described workaround with not deleting from the dvelop module works.
I hae never seen that problem in older versions
Working on Windows 10 64 bit.
Thanks for any advice
Try disabling the GPU.
Go to Edit > Preferences > Performance, and uncheck Use graphics processor.
If this fixes the problem, try updating your graphics driver, which may allow you to work with the GPU enabled.
