Short description of error
When using the refraction from screen space reflections, meshes to which a glass/Principled BSDF (with transmission to 1 and SSR on) shader is assigned get some artifacts when using rendered mode. Once I
renr it, the problem stops.

Exact steps for others to reproduce the error
Open a new file, select eevee, assign a Principled BSDF shader to the default cube, give Transmission a value of 1, activate SSR for this shader, activate SSR on the Render Properties tab and Refraction and then change the viewport to render mode.

Hi, thanks for the report. I can not reproduce on master: (4b31a21bcd19) and 2.93.6 (rB0930a70e8110)

I suspect that it's a graphics driver issue. Upgrading the driver will possibly fix the issue. Current version is little old so upgrading might help. can you please check that?
