Environment
AcuToWeb Gateway running in any browser on Apple CPU machines
Problem
When running a program in a browser using AcuToWeb, the program can show strange behaviour. Screens can close randomly, and the active entry field can switch randomly to another entry field. This doesn’t happen in the same browsers on machines with an Intel CPU.
Resolution
There seems to be some incompatibility with web technologies and browsers running on Apple CPU machines. The issue can be avoided by disabling hardware acceleration in the browser.
For instance, to disable hardware acceleration in the Chrome browser, follow these steps:
1. Open Google Chrome.
2. Click the 
icon in the upper-right corner.

Other browsers will have a similar process to disable hardware acceleration.
