3 tabs (1 & 3 icons have wrong rendering)
What is wrong with the rendering? 1, 3 and 5 tab icons blurred and used wrong size. See attached files and compare with original icons For example, first attached file, icon Computer: - on first line it's third icon blurred and not use pixel align - on second line it's second icon and looking good (as original) Caused by floating-point layout calculations in QtQuick. Not sure if rounding to full pixels is possible. (In reply to Christoph Feck from comment #6) > Caused by floating-point layout calculations in QtQuick. Not sure if > rounding to full pixels is possible. Is this possible in newer Qt versions? No, blurry icons at fractional scale with Qt scaling is still an issue in Qt, and it's not really easily solvable, if at all. See the extended conversation at https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/130#note_132515. It's possible that Qt could do some magic here to re-render icons to make them conform to the pixel grid better, but that's a real moonshot. Only a higher resolution screen will make this better, in general. That's been the approach of Apple and the smartphone companies: throw more pixels at the problem so that pixel mis-alignments become invisible. |
Created attachment 113667 [details] Tab icons + original icons Tab icons 1, 3 and 5 (left to right) - have wrong rendering. If change icons order position - anyway 1, 3 and 5 icons have wrong rendering. Possible for this tabs used wrong area icon size. Icons have 32px. Bug reproduced on Breeze Plasma Theme and other themes too.
