Caja does not resize desktop area after automatic resolution change #70

Closed jsane-h8ms closed 5 years ago

jsane-h8ms commented 5 years ago

Describe the bug My setup: Laptop with 2880x1620 display Docking station with 1920x1080 (or 1200) monitor connected bug

When docked, both displays use 1920x1080, for a total usable desktop size of 3840x1080. The resolution of my laptop display is automatically adjusted when docking or undocking (as it should), but the usable desktop area does not change with the resolution.

When docking for example, the added screen area to the right is usable for applications, but the desktop wallpaper is not redrawn, causing visual artifacts and I can not place desktop items there or drag a selection box with my mouse. (See screenshot and illustration, blue criss-crossed area is broken) screen

The same happens when undocking, (if the session was started docked) the added desktop area below is not usable (green area in illustration; in this case, the visual artifacts do not happen most of the time).

This is a regression from 18.1 (Mate GTK2 build; I skipped 18.2 and 18.3 with GTK 3 because of theming issues, so did not test).

To Reproduce Steps to reproduce the behavior:

  1. Get high-dpi laptop, dock and 1080p monitor
  2. dock laptop
  3. Adjust laptop resolution to 1080p
  4. undock laptop
  5. if neccessary, adjust laptop resolution back to native
  6. reboot
  7. dock laptop, wait for resolution change
  8. observe artifacts

Expected behavior Caja notices the new display resolution(s) and adjusts desktop area accordingly.

Frequency Happens almost always.
