Problem description: Tab-titles that are too long to fit into a tab get faded out.
|
|
On big endian this is broken and instead of fading out, the
|
|
tab gets white and the font transparent, leading to an unreadable
|
|
tab-title
|
|
Solution: This is not a real solution, but a hack. The real solution would have been
|
|
to byte-swap the correct buffer, but I could not find it.
|
|
So the next best thing is to deactivate the fading-effect. Now all tab-titles
|
|
are readable, albeit not as pretty to look at as they could be.
|
|
Side-effects: I have not yet found an unwanted side-effect.
