Slow tooltips while debugging

[jsteven]

I'm using tooltips pretty extensively in my Qt project. (Qt 5.12.2, using Qt Creator on Windows 10.)
While debugging, which I am currently doing 99% of the time, the tooltips are loading up very slowly, and in fact show up clipped at first, and then redraw correctly. While the tooltips are loading up, the debugger view of Qt Creator is showing a sequence of DLL's loading up. I think that the loading of these DLL's is slow for some reason, and is the reason for the painfully slow tooltips.
If someone could help me figure out something I might be able to change or fix to work around this slow loading, it would greatly help me with my development.
Attached is a screen capture of the loading sequence, and one of the DLL's names.
Thanks,
