After an upgrade from debian 10 to 11, maximizing windows leaves around a centimeter of space on the right side of the screen, while moving windows to the right using a binding (Move -0 keep Warp) does the same.
I realize this might not be an fvwm issue; the fvwm version - 2.6.8 - hasn’t changed, though on my upgraded system it’s compiled a year later than the 2.6.8 on another computer still running debian 10. My .fvwm2rc hasn’t changed either.
On the other hand, starting programs from the terminal with a specified -0-0 geometry does put them all the way at the right edge of the screen, and the wallpaper, which is set by feh, also covers the full screen. So it seems like fvwm might be getting display size information in a different way, and that way might be dependent on something that’s changed in the upgrade?
Any suggestions for what I can look at to track this down would be very much appreciated.
For what it’s worth (I apologize if this isn’t relevant) xrandr gives me:
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 16384 x 16384 LVDS-1 connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 277mm x 156mm
FvwmIdent on a “maximized” window gives:
Width: 1308 Height: 758 X (current page): 0 Y (current page): 0 Boundary Width: 5 Geometry: 858x663+0+0
If I move the window manually to the right edge of the screen, FvwmIdent gives the new X coordinate as +48.
DeskTopSize is 1x1. If I run a Pager, it shows the little strip of space at the right of the desktop that’s uncovered by open maximized windows.
