Freeze a few seconds when switch between schematic and PCB editor

[Kunpeng_Fan]

It is fast to switch but before I can move or operate any object in editor, the editor always freezes for about 4 seconds. It says "Kicad" is not responding. I didn’t modify anything. I switch editor by clicking “open in xxx editor” button in toolbar.

I found I can work around this issue by not putting the editors in fullscreen. It means it works well in small window size. It is quite strange.

I have a 5k screen and set display scale to 200%.

It is recommended to use X11 sessions with KiCad.

Wayland is not supported officially because of missing features and bugs.

For details on this issue, see Kicad very sluggish when some of its windows are hidden · Issue #23512 · wxWidgets/wxWidgets · GitHub

Setting environment variable ‘vblank_mode=0’ may help, potentially at the cost of higher power usage.

Note that other features, like infinite panning do not work on XWayland.

thanks for the work around. With ‘vblank_mode=0’, I am comfortable with current wayland mode.
