Shadow effects introduce performance issues #238

Closed juzzlin closed 1 year ago

juzzlin commented 1 year ago

There could be an easier way to disable the shadow effects (maybe just a button that sets the shadow parameters to zero) + probably we'd need a border color for the nodes to give some contrast.

juzzlin commented 1 year ago

Workaround for this is to go to File => Settings => Effects and set Shadow effect offset and Shadow blur radius to zero.

This at tries to fix the issue:

I had already disabled the effects, but that didn't change too much. The issue only arises when zoomed in for some reason. The full map with all the lines over each other is fast.

juzzlin commented 1 year ago

Could you please send or attach an example map with the problem so I could try to reproduce?

Restarting reduced memory consumption <200MB. Not sure the content had anything to do with it, had to clean it. It was mostly a maximum of 2 lines, most just one line, nothing dramatic.

Related to #141 ?

@l3td33r Looks like it. 4.1 with shadows off is definitely an improvement! Thanks for fixing the dragging by the way, that works fine now.
