Bug ID: 470023
Summary: QT_SCREEN_SCALE_FACTORS causes spectacle to completely
screw up screen coordinates.
Classification: Applications
Product: Spectacle
Version: 23.04.1
Platform: Neon
OS: Linux
Status: REPORTED
Severity: grave
Priority: NOR
Component: General
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: ---
Using the environment variable `QT_SCREEN_SCALE_FACTORS` to properly inform qt
of the different DPI of each screen causes Spectacle to overlap the images it
captures for the selection tool, furthermore the region selected doesn't even
match what is shown.
STEPS TO REPRODUCE
1. Launch spectacle with environment variable `QT_SCREEN_SCALE_FACTORS` using
different scale factors for each monitor
2. Try to take a screenshot
OBSERVED RESULT
Buffers captured for each screen are rendered at a scaled DPI (presumably from
the main monitor) causing overlapping when showing them and inability to select
intended region.
EXPECTED RESULT
Same behavior as if no such scale factors are in use.
