Qt6: Rendering of overlay TreeView is broken

@realthunder could you support here?

I don't get this background. Why not remove it?

Readability, models can have different color, have multiple lines etc so only way to ensure that tree items are easily readable in all scenarios is to provide background for items that will have good contrast against text and hide distracting stuff like lines fighting for attention around text.

Thats why Realthunder added the text effect.
If applied gently it's hardly vissible, but it does work.

[kadet1090]

It does not work well enough as with busy model it still is not readable enough, at least for me.

[MisterMakerNL]

Could you try the new added overlay stylesheets?
I had no issues, but also don't think much people tried it.

People have different tolerance for things being readable or not, depending on various factors. Realthunder implemented it (but remember, that he also implemented other options - including one with background) in the same way as movie captions are done - white text with black outline so it should be readable in every scenario. Unfortunately this effect is mostly effective with big text (bigger outline separating text from the rest of the picture), while we deal with small fonts. In our case we can also get a lot of lines with similar thickness in small area making it very busy and so needing more brain power to process it, requiring to focus on that particular area instead of being able to quickly scan it. I don't mind making the background optional - if for somebody background is distracting (which totally could be the case), I do however mind taking away option of having it.

This is not a thread for this discussion anyway, so let's not go off-topic anymore.

I managed to fix the issue, writeup on how: https://stackoverflow.com/questions/78414383/qt6-disable-drawing-of-default-background-for-qtreeview-items/78421604#78421604
