MySQL Bugs: #35407: Table box column name/data type extends outside the table at some zoom levels

Bug #35407	Table box column name/data type extends outside the table at some zoom levels

Description:
I noticed that some of my tables have text that extends outside the table box. I tried to reproduce this with a new schema diagram, but that seemed to work OK until I started to zoom in. At some zoom levels, the text is right at the edge of the box or outside it.

I suspect that zoom algorithm for the text is different than the table boxes. Text size is often scaled in discrete steps.

How to repeat:
1. Create a new schema with one table.
2. In the diagram, add a few fields to the table. Use long names and data types, e.g. acolumnwithalongname DECIMAL(15,2).
3. Zoom in and out in small steps.

Suggested fix:
The only fix I know is to allow some padding on the box size to allow for the expansion and shrinkage of the text. I suspect that the longer the string, the more padding you need.

Thank you for the bug report. Could you please provide the model file which
presents this issue and also your video settings. Thanks in advance.

For the model file, see the "how to repeat" section. You can create your own in the time it takes to add a note to a bug report.

For the video settings: 1920 x 1200 display size.

Thank you for the feedback.

I believe this has been fixed previously. I'm unable to repeat it anymore.

confirm, this has been improved during optimization of canvas code.
the issue does not appear in 5.1.16 anymore

An entry was added to the 5.1.16 changelog:

When zooming an EER Diagram, the text in a table would sometimes extend beyond the edge of the table box.
