A bit off topic but having trouble finding information about it.. "Show tooltips" option

[abclution]

This excellent plugin shares this option and likely runs the same background process for this option as the standard KDE Icons Only task manager.

I am having an issue and hoping someone more familiar with the code understands whats going on.

When I have many 9-10+ chrome windows open (with many tabs) hovering over the chrome icon literally pauses my computer for anywhere between 3-8 seconds until they are generated. The pause time is analogous to how many windows I have open.

Obviously this is likely due to the thumbnail generation of the poorly named "Show tooltips" option.

It seems that this thumbnail generation is a single threaded process (from what I can observe through htop etc..) and does not cache anywhere the results

My computer is a beefy 16 core AMD chip and feels like a turd when this happens.

I have failed to find the process and code responsible for this situation to see if there is anything that could be adjusted or fixed via a PR. Hoping someone here has more experience and can chime in
