I have a problem with the cursor hanging on PI3.
I am creating a project with QT with cross compiling, on PI3. I run it on the device. I click the button, the window appears, I close it and click over and over again for about 2-3 minutes. At some point the cursor freezes. I tested with the Buster, Bullseye and Bookworm versions of the system. The cursor always hangs on PI3. I couldn’t get suspended on PI 4. The earlier version of Buster from 2020 works properly on PI3, but unfortunately the new PI3 and new PI4 purchased do not start, the LED blinks 4 times slower, then 7 times a little faster. I know this isn’t really a VisualGDB problem, but I’m looking for a solution wherever I can.
