Description:
On integrated Radeon Graphics (Ryzen 5 5500U), hardware accelerated EER diagram renderer has a memory management issue that on large screen resolutions (3840 x 2160) causes the application to quickly freeze on files with many EER diagrams open at the same time.

The workaround is to check Force use of software based rendering for EER diagrams in Preferences / Modeling.

How to repeat:
On a large screen resolution (tested on 3840 x 2160) open a file with many (10+) EER diagrams and keep switching until memory usage reaches around 950 - 1000 megabytes, the application will freeze after that. Bug is hard to reproduce on 1920 x 1080 screen size.

Hello Julian Ragan,

Thank you for the bug report.
I tried to reproduce your issue on windows 10 with workbench 8.0.30 on a large screen resolution and opened attached file but I am not seeing any issues at my end.

Ashwini Patil

To make sure, you have used a machine with integrated graphics similar to the one I have mentioned in CPU architecture?

Maybe it is only related to latest driver version (30.0.13014.8 from mid 2021). made available by Dell for my laptop (vostro 5415).
