I noticed this issue with the footprint viewer. I’m using an old notebook to test the waters in linux, but I seem to be struggling with legacy support.
Notebook: Dell Precision M4300, Core2D 2GHz, 4GB RAM, Nvidia FX360M quadro graphics card, 1920x1080 15" display.
OS: Debian 9 (stretch) 64-bit
Graphics Driver: nouveau initially, now nvidia proprietary legacy driver 340.102.
KiCAD version: 4.0.5, 64-bit. This is the latest I can get through the vetted repositories. I looked for 4.0.6 but no luck.
Under nouveau, the 3D performance of KiCAD was actually very good. The performance of streaming media OTOH was terrible. I could not view a video @480p without frame dropping, never mind expanding it to full-screen. So I turned on hardware acceleration in the browser. This fixed the streaming issue, but caused the laptop to freeze for several seconds, then reboot. If I turned off hardware acceleration in the browser, sadly it still would crash when using KiCAD’s 3D viewer, or FreeCAD (I was trying to create a 3D model for KiCAD) just not as frequently.
Under nvidia, streaming video is great, no crash/reboot cycles, but… now the 3D display in KiCAD (and FreeCAD) is super slow, not usable. It looks like the OpenGL rendering is not being pushed into the nvidia card.
I can either have good KiCAD performance and unusable video with occasional crashes, or I can have great video but unusable KiCAD 3D/FreeCAD. I am not sure where to turn, or if this forum is just the wrong place to ask for advice.
Thanks in advance for any knowledge shared.
