David, Nate, Josh, Marco, Carl, and Niccolò are here ready to answer all your questions on Plasma (all versions), Gear, Frameworks, Wayland (and how it affects KDE’s software), and everything in between.
Fire away, Lemmy!
We were expecting to be done in an hour and we have past the 2-hour mark already! Time flies when you are having fun.
Thank you for all the questions and the welcoming and friendly atmosphere, but the devs must get back to making Plasma 6 great.
Please keep the conversation going and KDE contributors will continue to answer over the next days as time permits.
Thank you all!!
@Bro666 With the transition from QT5 to 6 and Plasma 5.27’s implementation of wp-fractional-scale-v1, will most KDE apps now be able to fractionally scale without using the upscale-downscale method? (Or in other words, how QT apps fractionally scale under X11)
That’s correct!
@davidre While KDE doesn’t oversee LibreOffice development, since they also have a QT6 backend for their UI, might they also benefit from this? Currently fractional scaled LibreOffice under Wayland with the QT5 backend is extremely laggy, presumably due to the upscale-downscale method.
LibreOffice uses its own toolkit called VCL which uses a number back-ends to render using native toolkits on all platforms, similar in concept to WxWidgets. I don’t know if the way VCL works allows Qt6 fractional scaling to just work, but a Qt6/KF6 back-end already exists and can be forced by setting
SAL_USE_VCLPLUGIN=qt6
orSAL_USE_VCLPLUGIN=kf6
, so you should be able to try it out right now.
