Crowded COM buffer with UDP

[MajklS]

Hi, I have such a problem, I really don't know how it could be affected.

I send 100 logs per second to the program via UPD protocol, if I have a mouse that is in the decoration window, the COM buffer will not be overfilled, but if I have it outside the decoration (on the main panel), the COM buffer will be overfilled.

Why does it affect where the mouse cursor is? It's very strange.

In addition, the COM buffer is from the RS232 port, I don't understand how it relates to the UDP protocol.

It also affects the timer. When I have the timer set to 1.00s, the buffer does not overfill, but the buttons work poorly with some delay.

When I have the timer set to 0.03s, the buffer is overfilled, but when I have the mouse in the decoration window, the buffer is not overfilled, so they have no delay and the buttons and recording work. Does it have anything to do with it?

Thank you for help.
