when opening tickets in our helpdesk system, TeamDynamix, the new window opens on the main display. if the Firefox browser is open on another display the new window has empty space on the right and bottom (see attachment). if the Firefox browser is open on the main display or the new window opens on the same display as the Firefox browser there is no empty space. dragging the new window from the main display to the display with the Firefox browser open the empty space disappears and the new window displays correctly. this only happen recently. with an older version of Firefox (not sure which version), there was no empty space on the new window. laptop: HP Elitebook with an external monitor laptop built-in display (main), external monitor (second) Firefox Version 107.0 (64-bit) Windows 11 Version 21H2 (OS Build 22000.1219)
