Nvidia driver 390

Nvidia card GF108GLM (NVS 5200M)

Pd 0.52.1

Gem 0.94

When I open a gemwin the display stops responding. I have to kill Pd from outside the window manager to get control back. I tried switching to the nouveau open source driver but that is unusably laggy on this machine. There appear to be no other versions of the nvidia driver that work with this card (tried 515, 510 already). All other OpenGL apps such as GLXGears seem to work fine. Shutting off "sync to vblank" did not help. I'm at a loss as to what to try next.
