One of our customers has a problem opening a window on his Amazon AWS Appstream system runing our Powerbuilder appication.
At the moment, only one window is involved. It's a standard window (99864 Bytes) nothing special in it.
Powerbuilder falls into"Not Responding" and consumes 50% of the cpu without ending.
The application works well outside the Appstream environment.
For the moment we have tried unsuccessfully to update Windows redistributable c++ to (2015-2019) and we have increased the heapsize to 1024/20408/2048.
What can we look at?
Thank you in advance for your help.
