There are graphical issues.
1: please notice how resizing the window does not resize the contents.
2: I cannot click/edit any of the numeric values of the pad
I have also tried to use : flatpak run --env=GDK_BACKEND=x11 org.kicad.KiCad to run it, the issues vary, not always reproducible at first time, but they are there.
3: thank you, on this computer, using flatpak run --env=LIBGL_ALWAYS_SOFTWARE=1 --env=MESA_LOADER_DRIVER_OVERRIDE=llvmpipe org.kicad.KiCad seems to make everything work fine.
Please note that running in software mode does not fix everything, I can get some ghosting around windows, footprints may not be grabbable unless I close/open PCB editor, and menus disappeared, some items cannot be clicked etc. I plan to get Nvidia GPU on the workstation (as home, where everything works fine)
Application: KiCad Schematic Editor x86_64 on x86_64
Please note this super-strange behaviour:
I can open and close the About window, or just interact with it - but at some point (0:57) in this video, you can see all tabs unresponsive and ādisabledā they are not responding to mouseover, and do ot respond to clicks - but then I move mouse down to the text area, and scroll! - then the last clicked tab may work.
I do not longer believe this is related to the X11 variable.
Same issue on my end. The issue seems to be linked to capturing the mouse input. I have a similar issue in PCB Editor and during Schematic entry. After some time, mouse inputs just stop working. It seems that at some point the mouse events (e.g. movement) stops working. i.e. the crosshair is not following the mouse anymore. Also selecting things doesnt work (e.g. click, then drag an area, then let go).
I am aware of mouse button gremlins⦠I was close to buy a new mouse due to that , but it disappeared ! If the button stops to work as expected, then it is not related to KiCad. But I donāt know the guilty.
For Wayland, you must provide the compositor (Gnome, KDE). X11, Wayland, and kernel have tools to debug/log inputs.
Running on a stock Ubuntu 25.10 with Gnome. At the end of the post you can find the version string from the About dialog. Next to mouse issues, there is also a rendering problem as pointed out earlier. At some point the redraw/update of widgets and canvases doesnt work anymore. This also happens with standard wxWidgets widgets, i.e. in the project manager. When it is in that state, you can still interact with Widgets as also described earlier. I.e. in the about dialog you can clock buttons but the GUI simply doesnt render the resulting appearance.
i have investigated this further and this is a wxWidgets issue in the wxAui part. If you install wxWidgets 3.28 and build an AUI example, i.e. as from the website below, it shows the exat same issue. A basline wxWidgets app without AUI doesnt seem to have the problem
I now see that PrusaSlicer ās Preferences menu has the same issue. For all other applications I tried, this works fine. It could be that this is something that KiCad and PrusaSlicer does something differently that triggers this bug. (not necessarily that the bug is in those two applications)
Actually, it is mandatory to describe the full stack. For example, you have a GTK version that implement a Wayland protocol v1 and KDE is already implementing v2 thus it cannot work⦠And the bug happens because you are using a different setup that the one used by the developer.
