Hi, <span class="colour" style="color: rgb(60, 64, 67);">For about a month the 3D visualization of the PCB has been very slow, with each change of view the refresh takes place after many seconds. This happens for all projects, even the older ones where the visualization was perfect and fast (in real time), so I do not think the issue is project related.</span> <span class="colour" style="color: rgb(60, 64, 67);">My operating system is Windows 10 latest release.</span> <span class="colour" style="color: rgb(60, 64, 67);">Thanks in advance.</span>
