I’ve been migrating a C++ Coin/Quarter project to Qt3D. I’m doing this on a newer iMac/Catalina. The graphics performance seems unacceptable. A simple display of 3600 line segments takes about 5 seconds to render and 30k segments takes >30 seconds. When the rendering is started, Qt puts out

If you're goint to change to 5.12, you might want to wait a month or so for 5.15, the next LTS, is targeted around May 15.  I'm not sure how much work it is for you to switch, but if you're just now switching to 5.12, I assume it is at a substantial cost...       Sent: Monday, April 13, 2020

Some database engines allow you to set properties of a database transaction, like read only versus read/write, isolation level etc. It looks like in Postgres you would use an SQL command line like 'start transaction isolation level repeatable read;'. In Firebird/Interbase, you have to parse
