Thanks,
digitalsoapbox for the support. Which windows version and build are you using?
In my case "Don't show unique icons" option reduces the lag significantly. But this can not be considered a solution or workaround, as not having unique icons HUGELY affects the usability.
Is anyone wants to test if your system is affected, here is the batch script that I used.
Download this capx, create a text file in the same folder, name it RunAgain.bat :
start test_lagging_win10.capx
timeout /t 40
taskkill /IM Construct2.exe
timeout /t 10
RunAgain.bat
[/code:u9erp6dy]
Run the bat file. Take a note how many seconds does it take for C2 software to open. Leave the script running and go have some lunch or dinner
Check again in 30-60 minutes to see if C2 startup time has increased. And then test if there are any lags with opening event dialogs, context menus, sprite editor etc., similar to this [url=https://youtu.be/8thpozIBnUU]video[/url].
