--- Comment #7 from Waqar Ahmed <waqar....@gmail.com> --- Yeah, tab are treated differently. The problem is that the file you linked contains way too many trailing spaces in each line (2000+ sometimes). So, if you want to keep the spaces setting enabled, a good local fix would be to just rtrim the whole file by - Hit F7 - type "rtrim" and press enter This can be optimized in theory as the width of a space is constant. We can just use that to quickly paint all the spaces. Problem is that dynamic word wrapping makes things a bit trickier. Maybe we can use something like QTextOption::ShowSpacesAndTab + draw the spaces ourselves. That makes it a bit easier to optimize this case. ---- For part 2 => slow paste, I think this is because of "Indent on Paste". Do you have it enabled? Your profile data shows that it is enabled, but maybe its something else. I am not sure why indent on paste is getting executed on a `.log` file in the first place as it doesn't have an indenter. -- You are receiving this mail because: You are watching all bug changes.
