Migrated from https://bugs.launchpad.net/inkscape/+bug/386627 #### Steps to reproduce: <!-- Describe what you did (step-by-step) so we can reproduce: --> 1. Open the [ColorMatrixTest.svg](/uploads/bdfc46f7654c6397f628a8ab6982f572/ColorMatrixTest.svg) 2. Open the Filter editor. 3. Select the second color matrix in the list, and modify the bottom right field (also works with other entries). 4. Select the third color matrix. Not that the bottom field is set to 0. 5. Select the first color matrix, and then the third one again. #### What happened? - After the last step you see the matrix for the second color matrix, although the third was selected. - It's just a filter editor issue, and the XML code is not affected (unless you edit the matrix while it is wrong) - Relates to https://gitlab.com/inkscape/inkscape/-/issues/1225 #### What should have happened? Filter primitive values should always be updated to the currently selected filter primitive Sample attachments: [ColorMatrixTest.svg](/uploads/ca6c67c8fc8cfd2963539cd3a0069f96/ColorMatrixTest.svg) #### Version Info: - Inkscape 1.1-dev (5c7c05abd9, 2020-10-19) Linux Mint 20 - Inkscape 0.92pre1_64bit r15016 Windows 7 - Inkscape trunk revision 10123 Windows XP - Latest 12 june 2009 win 32 build
