[Chimera-users] Frame rate drop with viewing panel open

[Daniel P Farrell]

Hello,

I've been using chimera for a long time now, and I always thought there was
some sort of memory leak because it was so slow after 30+ minutes of usage.

Today I started a new session and somehow discovered it wasn't a memory
leak, but the viewing panel!

This is on Ubuntu 18.10

I'm 'guessing' it's the side view sapping some computational power? but my
CPUs aren't maxed out, and my GPU is also showing low usage so it must be
some strange bug.

Here i load the benchmark window and set it to continuously measure frame
rate:
>>> happily twirling large structure + lots of molecules
Frame rate: 61.6
Frame rate: 60.0
Frame rate: 60.0
Frame rate: 60.0
Frame rate: 59.9
Frame rate: 60.0
Frame rate: 60.0
Frame rate: 60.0
Frame rate: 60.0
Frame rate: 60.0
Frame rate: 60.0
Frame rate: 60.0
Frame rate: 60.0
Frame rate: 60.0
Frame rate: 59.9
Frame rate: 60.0
Frame rate: 59.8
>>> open viewing panel by clicking 'side view' icon on sidebar + continue
twirling
Frame rate: 29.6
Frame rate: 27.1
Frame rate: 11.8
Frame rate: 19.4
Frame rate: 19.7
Frame rate: 19.7
Frame rate: 24.0
Frame rate: 30.0

Even though I know ChimeraX is the main focus now, I would love this to get
fixed!
