Created attachment 150961 [details] screenshot When you use translucent color on editor background text area, all lines with filed text have own background fill, which is definitely not the expected behavior! Included screenshot! Icon border background work like expected, but again separator line have double file on right side of line? Can you please fix this? Thanks!
This is working as expected and I don't think it will be changed.
One can keep it as a wishlist, but if nobody steps up to implement this, nothing will happen. We never supported transparency.
Created attachment 154063 [details] ktexteditor nonsense https://invent.kde.org/frameworks/ktexteditor/-/blob/master/src/syntax/katethemeconfig.cpp#L422 You obviously support! But support or not, it just shows that somehow render is broken. And there would be no problem at all if ktexteditor will just adopt application backgound. Now if we set text area background to full transparent, (#00000000) to avoid double filling background in lines, ktexteditor view become transparent with desktop background. Included screenshot!
Then dave.nextgen@gmail.com please provide a non-breaking patch to make transparency work for the background of the rendered lines. The code for rendering lines is complicated and has not been designed with transparency in mind. And it seems that this is not an itch or big issue for the current volunteers developing Kate or KTextEditor. Thanks, Kåre
If somebody provides a patch, all fine, I don't think anybody of the team shall waste precious effort on this.
