I’m experiencing a large lag in cursor movement and draw update when moving items in Pcbnew. See attached screen record.
I’m using Modern Toolset (Accelerated) (F11) however changing this does not eliminate the problem.
OpenGL appears to work fine since the 3D viewer runs smoothly. My graphics card driver is up to date.
For this release version of KiCad I don’t experience this lag in Eeschema when doing move operations however when I tested the latest nightly build (7/12/2019) both Pcbnew and Eeschema did display this lag problem.
KiCad Version : (5.1.2)-2
System info: Windows 10, i5-4460, 12 GB RAM, GTX-1050 Ti
Anyone have any ideas on what could cause this or is this amount of lag to be expected?
The amount of lag seen in the video is not expected.
I have seen issues with some Windows installations that slow down redraw operations. Usually it is a graphics driver issues. Sometimes it can be caused by putting KiCad or the KiCad files on a shared drive. A few times, KiCad operations were being sandboxed by an AntiVirus software.
Check these things first. If they don’t apply or changing them doesn’t fix your issue, please report this over at the bug tracker. https://bugs.launchpad.net/kicad
Seeing the same issue with KiCad 5.1.0 through 5.1.4 (not tried older) on my machine. One of my CPU cores is pegged close to 100% when dragging the component, if you repeat circular motion drag it just doesn’t update the component location until you stop.
Running latest Windows 10, Ryzen 1700, 16GB RAM, GTX 1080, tried various nvidia drivers, with clean removal and install, also completely removed KiCad and reinstalled several times.
It used to run just fine on 5.1.0 and 5.1.2, think it was after a windows update that it stopped working properly.
