Developer tools is SO slow

I’ve been working on a custom theme, mostly for my own use, and struggling with how painfully slow the dev tools screen is. To the point where it takes up to a minute to select a node and see the CSS that is being applied to it. The entire app is slower or even freezes up once I have dev tools open, so I basically can’t edit text or navigate around the graph at all.

Obviously this makes theme development pretty painful. Have others experienced this or have any suggestions?

My graph is around 1200 pages and I almost never open the graph view or use features like whiteboard etc.

Try starting with --disable-gpu to check if it helps.

I think some of the newer optimizations done by browsers perform very bad on some older hardware. If for example firefox runs and the webrender backend is on, my whole desktop performs poorly.
