Can you attach an example PCB design to this bug?

This happens with a new blank PCB - File->New Project, Tools->PCB New

I can't reproduce. Maximize works just fine for me.

Interesting. Full trace, if that helps.  I'm using https://github.com/cscashby/faderboard/blob/master/hardware/board-controller-2560hat/board-controller-2560hat.kicad_pcb if that helps.

Not sure how to open that file. Anyhow, I suspect it's related to the resolution of the X server. Can you attach the output of 'xrandr'? What is the zoom factor you use in chrome://settings/display ? Do you have an external monitor attached? Does it repro if zoom is 100% and no external monitor is attached?

It's more nuanced than that I've now realised.

At 100% on Pixelbook only all works fine.

At 70% (or with other HiDPI monitor) it will crash. UNLESS you've previously opened the app at 100% and resized or maximised the PCB window (deleting ~/.config/kicad proves this).

It seems that the PCBnew window is getting some invalid hint from WX about available size and crashes. If a ~/.config/kicad has previously had sane values in it it works fine.

xrandr at 70% (which is first report):

Screen 0: minimum 320 x 200, current 3428 x 2285, maximum 8192 x 8192
XWAYLAND0 connected 3424x2285+0+0 (normal left inverted right x axis y axis) 544mm x 363mm
   3424x2285     59.97*+

Switch to 100%:

Screen 0: minimum 320 x 200, current 2400 x 1600, maximum 8192 x 8192
XWAYLAND0 connected 2400x1600+0+0 (normal left inverted right x axis y axis) 381mm x 254mm
   2400x1600     59.95*+

Is this still a problem in the current version?

Still occurs in 10895.78.0 (Official Build) stable-channel eve
