"select tiles" tool will lag horrible after IDE has been open for a while

[gm-bug-reporter]

Description

when opening my project and using the select tiles tool. To copy paste tiles around it will occassionally be very slow. I will hold the mouse down, drag to a new location. And then wait for the selection to actually happen before i let go. This can sometimes take a whole 10 seconds. So it basically becomes unusable

Steps To Reproduce

Open a project with a lot of tiles, try using the tile select tool. Notice the bad lag. If no lag occurs, wait a few minutes, sometimes it works fine when the ide is freshly restarted.

here is an example. It took about 25 seconds to make a simple selection. Making tile heavy levels, with this is unbearable
