Created attachment 129113 [details] Dialogs with small shadows OpenSUSE Tumbleweed with Qt 5.15 and all KDE software built from today's git master. STEPS TO REPRODUCE 1. Set scale factor to 200% 2. Reboot 3. Open Kickoff or any other Plasma dialog OBSERVED RESULT Shadows do not scale and are super tiny EXPECTED RESULT Shadows scale and are normal sized
Not a problem on Wayland.
This seems to have been fixed recently.
Hmm, this started happening on X11 again. Seems to semi-randomly toggle on and off.
What's actually happening is that shadows look correct on Wayland, and then when I log back into my X11 session, the SVG cache isn't cleared, so I have correct nice-looking appropriately-scaled shadows on X11 until the next cache invalidation or manual cache clear event. So the display of correctly-scaled shadows works fine in X11, it's just that whatever is generating them in the first place isn't scale-factor-aware. Seems like it might be an easy fix.
This is caused by using Qt scaling on X11, which is not supported cna is known to cause this kind of bug. Sooooo don't do it. :)
Re-opening to refresh the blocking status since Bug 356446 is also re-opened.
Moving to plasma-framework since that's where the bug is.
The thing this is a blocker for (Bug 356446) is closed now, and doing this was never supported anyway. Unfortunately I think we have to close this. Folks who want a decent hidpi experience will have to use Wayland and look forward to upcoming changes to improve the experience for XWayland apps in particular. Sorry everyone. :(
This can be fixed by rounding up devicePixelRatio in framesvgitem
