Very strange performance of QLabel and QLineEdit
-
Hi,
I have a program with simple QLabel and QLineEditinside a QGridLayout. On a particular computer, anytime I change a QLabel by setText or anytime there's an input in a QLineEdit, the program freezes for around 250ms to 300ms. This behavior does not happen on other computers, including weaker ones. CPU utilization goes from 0.5% to 2%.Computer CPU that has problem :
- AMD 3600x (6 core 12 thread) + Rx580 GPU
Other CPU that has been tested with the same program and works well :
- Intel i3 5th gen with integrated GPU
- Intel i5 8th Gen with integrated GPU
- AMD 5900x + 1660ti
Anyone has had similar issues before?

No
Does changing label or the line edit trigger any activities in your application?
Can you debug your app on that machine? -

Hi,
Are you graphics driver up to date ?
If so, did you try with an older version ?
