Major problem with a GCP workflow in version 1.5.3 build 8469. Whenever I open a photo to either add or edit a marker, the screen does not refresh. The photo hangs and you have to hit the 'Model' tab and return to the 'Photo' tab to see the refresh. If you try to grab a marker to adjust it's position, the mouse cursor disappears. You again have to hit the model tab to see where the marker landed. Also, the little zoom window that appears as you adjust markers is not visible. Of course this is not a workable option for a GCP workflow!
This is on a slightly older Lenovo machine. I7 processor, Nvidia GTX980 and Intel HD 4600. I've tried multiple things in the preferences. I've turned one or both GPUs off, checked the CPU option lower down, even tried High DPI mode. I've had the raw photos both on an external and internal SSD. Same result always.
Is there a solution?
