Problem Description
You are experiencing growing GPU memory (VRAM) usage in COMSOL Multiphysics while switching between between plots, while using plot while solving, or while having convergence plots enabled.
Solution
This issue has been observed for a few NVIDIA card and driver combinations when using OpenGL rendering.
Try the workaround to set Threaded Optimizations to off in the Nvidia Control Panel under Manage 3D Settings . This helps in most cases.
You can also try switching to software rendering if the above does not help. Open Preferences, and go to the Graphics section, and set Rendering: Software.
If you have run into this issue and need hardware rendering with OpenGL, disabling plot while solving and the convergence plot should improve the behavior.
