PopUp opens character sheet to width of monitor

[mjeffw]

In my system (GURPS), the default character sheet opens in PopOut! to the entire width of the monitor. See the attached photo.

Other character sheets seem unaffected, so I am sure this is my fault somehow. Any help in finding the issue is appreciated.

Just FYI -- doing some debugging on this shows the following div:

<div id="GurpsActorSheet-Scene-FDCd4uMWjnhniOmd-Token-YcUsx8PqiOyt0IIw-Actor-fLdFl7mPT4V98udO" class="app window-app gurps sheet actor" data-appid="27" style="display: flex; top: 0px; width: calc(100% - 9990.5px); height: 100%; margin: 0px !important; border-radius: 0px !important; cursor: auto !important;">

That "width: calc(100% - 9990.5px)" style looks like the cause.

I haven't had a chance to test it myself, buy try enabling/disabling the bounding box compatibility mode. I had to switch that to enabled by default due to dnd5e basically requiring it with the latest update. If that fixes it, it's usually because an element in the sheet has a fixed/absolute position very far to the left of right of the screen (and not contained in the bounding box of the sheet)
