Please open task manager and check if any cpu processes are using a high amount of cpu when this happens.

Do you have rainmeter or wallpaper engine installed?

CPU load goes from 1% to about 14% only during the first toolbar launch. After that, the toolbar works fine, and launching it again doesn’t cause any additional CPU load.

No rainmeter or wallpaper engine installed.

I needed to see what was using the cpu at 14%. Please show what process that was.

Looks like snipping tool is causing this. Do you have clipboard monitoring enabled? Try disabling it.

pyrates999 avatar Oct 21 '25 10:10 pyrates999

No, snipping tool has nothing to do with it. That´s intialising snipping tool before clicking the toolbar button. There is no striking peak except Defender.

Wait until the cpu goes back to 0 and then try opening it.

pyrates999 avatar Oct 21 '25 13:10 pyrates999

That´s exactly what I did.

nexusV2 avatar Oct 21 '25 16:10 nexusV2

I think the delay is happening is because windows is having to cache all the items before showing it.

pyrates999 avatar Oct 21 '25 22:10 pyrates999

Any idea how to address this issue? All my attempts to prefetch toolbar icons after Windows 11 boot have failed. Exclusion from Defender didn’t help either.

I think this is just by design by Microsoft. Good luck in finding an answer.

Can you reproduce this behaviour with an own custom toolbar?
