Trouble when opening two linked GUIs

AFNI Message Board

Hi all,

I have been working with two linked-GUIs to compare images. However, one of the GUIs randomly disappears when working on it (the image sections stay). This only started happening when I upgraded my IOS to Ventura.

Any suggestions?

Thanks,
Lena

I’m going to assume you mean MacOS Ventura (13). I’ve seen something similar and strange years ago with El Capitan, and how it deals with multiple (2) monitors. Take a look at the advice from back then regarding the sometimes strange interaction of MacOS with XQuartz.

I haven’t had a chance to try Ventura yet, but it also may be that Ventura has some problems with external monitors, possibly intermittently. You may want to see the effect of HDMI vs Thunderbolt connections, reduced resolutions/colors.

Yes, I mean MacOS Ventura (13). This issue is actually occurring without the use of any external monitor. Any suggestions?

Thanks,

So that’s weird. There is a related XQuartz/MacOS bug that seems to have disappearing windows. Cmd-tab twice sometimes brings lost windows forward. The posted fix seems to be with the MacOS to 13.3. Also update XQuartz to latest version.

I may be able to test next week on a Ventura system, and try to explore this further.
