yes, of course, it's important to check all updated system resources or modules for possible new bugs, issues or conflicts, and I'm indeed very glad that at least a few users, like you, are still doing these tests, send bug-reports and offer their help for troubleshooting, because I don't have real Amiga hardware in use anymore.
Btw, did you already notice that Thomas Richter has made an (older) update of the layers.library publicly available
. It's waiting now to be tested:
Please remove other patches for layers.library from your system before you try this update.
