Friedrich W. H. Kossebau <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #2 from Friedrich W. H. Kossebau <[email protected]> --- Hi. The last days some issues with the scaling done inside the folder thumbnail rendering code were uncovered, which might explain the issue as documented in the screenshots, though under certain conditions only, which also would be a bit unexpected. Which might need some more investigations into your system, so some questions: a) can you tell the output of "kscreen-doctor -o", especially the "Scale" values shown for the respective outputs? b) had you added/removed screens during the respective apps (the one where you used the file picker and Dolphin) were running? c) had you moved the windows around between your screens? As by your screenshots the pixellation is limited to the overlayed file thumbs, not seen with the folder itself, a possible cause currently can be if the thumbnail worker assumes (for unknown reasons) all screens have no scaling (or, have 1), while the apps run with scaling of e.g. 2 and request a scale-matching thumbnail. In case you are experienced with running code from git, please check https://invent.kde.org/network/kio-extras/-/merge_requests/556, which has been merged to master as well the release branch already, so what will become 26.08.2 in October. And in case you have developer skills, please also consider adding qDebug() << "APP devicePixelRatio" << QGuiApplication::devicePixelRatio(); to the begin of ThumbnailProtocol::thumbForDirectory() method in https://invent.kde.org/network/kio-extras/-/blob/master/thumbnail/thumbnail.cpp#L529 locally, so we can see what the worker thinks the scaling is. -- You are receiving this mail because: You are watching all bug changes.
