--- Comment #10 from Jeffrey Bosboom <jeffreybosb...@gmail.com> --- I have found a workaround: - launch KDevelop - open the qt5ct configuration tool (`/usr/bin/qt5ct`) - go to the Troubleshooting tab (all the way on the right) - check the "Force raster surface" box (note this is a tri-state box, make sure it's checked) - click OK or Apply - wait a few seconds As long as KDevelop remains open, almost all of the interface is correctly themed. The only exception I see are the editor tooltips that show semantic information when hovering a variable/function/etc., which are still black-on-white (light). If I close KDevelop and re-launch it, it uses the default light theme again, and I have to re-run `qt5ct` and click OK (no actual changes necessary). The "Force raster surface" checkbox is a global setting, not tied to any particular application, but it doesn't seem to have any negative effects on Picard (the only other Qt application I use regularly). The tooltip for the "Force raster surface" checkbox is "Make top-level widgets use pure raster surfaces, and do not support non-native GL-based child widgets." KDevelop doesn't appear to be making special use of vector graphics or OpenGL, so I'm not sure what this means, but maybe it's useful information for you. -- You are receiving this mail because: You are watching all bug changes.
