I read a lot about problems regarding getting this popup dialog - for me it happens rather often. The solution seems to be to update the graphics card driver. I have to an Onboard AMD Radeon Graphics unit (part of the processing unit) and a NVIDIA GeForce GTX 1050Ti. Both units have the latest drivers installed that are available.
The point is that once I get this pop-up I have to force close KiCad via Windows Task manager and doing so I loose content if I have not saved the second right before.
If I e.g. get the popup after opening the 3D Viewer the popup shows up and no matter how often I will click “ok”, it respawns. The schematic and board windows of KiCad cannot be accessed so that I could save recent changes before force closing KiCad.
I think that in no case should this happen (no matter whether I have the newest graphics card driver or not, I should be able to close that popup and gracefully close/restart KiCad, right? =)
Oh, sorry - just Windows had the opinion that I had the latest driver. Thanks for pointing that out. I will now install the latest version yuo have pointed me to and try again a few times. Also I just have changed to “high-performance GPU for all KiCad binaries”, i.e. it should use the NVIDIA Card now
I have the issue more or less in all “tools” (schematic, pcb, 3D viewer) - it happens sporadically but rather often (every 30 minutes or so)
CPU is an AMD Ryzen 5 5600G with Radeon Graphics, 3900 Mhz, 6 Core(s), 12 Logical Processor(s)
With explicit “high performance” settings for tue kicad binaries, i.e. making explicit use of nvidia geforce that is in the PC, the errors seem to be gone.
With “automatic” setting (letting the OS choose which defaults to AMD onboard) shoes the error also with newest AMD drivers.
Have to investigate further …
