If we have relatively large (512 x 4 byte) arrays in debugger watch window then it takes a lot of time to update the value of these variables.
The delay is caused by GDB reading long arrays one element at a time.
Presently, there are no Creator releases planned anytime soon resolving this issue..
Moving the arrays to another scope (such as global variables) might prevent them from being displayed in the Locals window.
If you feel above is not your case, please share the project in order to recreate the issue.
I am not able to share the project due to proprietary concerns, but this is not a case of reading back memory. There is nothing in the watch window. The only windows open are Output and Notices.
I've been bitten by the large array problem in the past. This is different.
