List View for Studio Palettes (green icon with s at the bottom) seems to be broken (black bars) ?

[Bracket-H]

Description

List view for studio palettes (or palettes that have references to other colors? More testing needed) is broken.
It only shows the first entry and the rest is messed up black stuff.

Palettes which aren't 'studio palettes' are unaffected

The only way to see other colors is to scroll them into the first place

scrolling down so that another color 'scrolls up' into the first position:

I have noticed that since my last Linux update, that I have had trouble with GTK apps...their windows needing a resize to show up correctly.
But OT is a Qt application...so I'm only adding this detail for completeness sake.

Steps to Reproduce

1. Choose a studio palette from the palette window
   or
   1.Right click a non studio palette and choose "Convert To Studio Palette and Overwrite"
   2.Receive broken palette display

The colors themselves are not messed with, it's just the display.

Expected Behavior

OT making me a coffee and a sandwich...
Just kidding (partly)
For the colors to be displayed correctly.

Also, if it's not that obvious:
All other display modes work fine.

I don't know the exact relationship, code wise of the things but...it seems that this bug affects color styles that have a 'text reference' to some file.
Like how that one from the Rsater Drawing Palette points to my projects folder in my documents.
or how one points to
color 0 'Global Palettes/Mictlan Colors.tpl:0'

Whereas normal (level?) styles (the ones with the amber colored icon...are fine.

I'm going to try to mix styles...forgot how that's done lol so...I'll make another post once I've figured that out.

Weird... once loaded into a level, it displays fine it seems?

I can reproduce but only on Ubuntu, it works fine on Windows.
