Sorry for my ignorance, however I decided not to show all the code used nor discribe all to steps needed and used to make an event be handled on the GUI. I was hoping you would take the " All of that is verified with less load." as a sort of proof.
IMHO it has to be a "not refreshed" display, otherwise the click on a "not visible" button wouldn't be possible (Isn't it weird to click "somewhere" and the not displayed Button is working?)
The .Refresh also works for the picturebox, which normally gets filled over time, however in heavy load the updated wasn't shown as it was calculated but only some time later but with the complete misssing history at once.
BTW, I tried an .Invalidate for the whole UserControl, which didn't work for both observed problems, .Refresh did work!
