Description tmacalp 2015-01-28 03:40:23 UTC
In LO 4.4, it's now possible to somehow set the transparency of frames >100% if you use the field in the sidebar.  Once set to this invalid value, if you click off of the frame and then back on, transparency option will be greyed out in the sidebar.  At this point it's easy enough to work around it by just pulling up the normal frame properties dialog.

Steps to reproduce:
1. Create a new document
2. Insert -> Frame
3. Pull up the "Properties" deck of the sidebar
4. Either type in or use the "increase" button to set the transparency higher than 100%
5. Click somewhere other than the frame to set the value

The box should have an upper constraint of 100%.  It should not let a user set a higher value.  If it somehow is set to be higher, it should fail gracefully and set the transparency down to 100% while not disabling any transparency options.  It should behave the same way the transparency tab in the frame properties dialog behaves.

The transparency settings in the sidebar are disabled and impossible to correct without changing the frame property settings.  The settings show a greyed out value of 50%, though the frame acts 100% transparent.

At least this value seems to go through a sanity check while loading the document and invalid values don't survive a file reload.

I tested this using LibreOffice using 64bit Arch Linux.
