Bug ID: 487859 Summary: In wayland, drag&drop does not reliably work for [GIMP, Krita, Discord] when using scaling factors greater than 100% Classification: I don't know Product: kde Version: unspecified Platform: Manjaro OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: unassigned-b...@kde.org Reporter: tamius....@gmail.com Target Milestone: --- SUMMARY When dragging files between two programs, when at least one of the monitors uses a scaling factor greater than 100%, some programs develop zones where drag&drop doesn't work. The size of this "dead zone" depends on scaling factor and window position. This could be an issue with Xwayland (as it seems very program-dependent), but I can't say for sure. DISPLAY SETUP Left monitor: 5120x2160, 60hz, 150% scaling, Right monitor: 3440x1440, 144hz, 100% scaling DETAILS: With the setup outlined above, I tried to drag files from Dolphin into a target program, which were installed from official Manjaro repos (extra) unless noted otherwise. The "problem programs" are GIMP, Krita, and Discord. When dragging files into these programs, I should be able to drop files anywhere in the window. However, this isn't the case. Programs will develop dead zones on the left and top side of the window. The size of dead zone depends on window position and scaling factor. For example: If I put GIMP, et al window on the left half of my left monitor, or maximize it, then drag&drop will work as expected. However, if I put the window on the right half of my left (150% scaling) monitor, then the left ~half of the window¹ will NOT accept drag&drop ("not-here" cursor appears). If I repeat the same experiment at 125% scaling, then only the left ~quarter of the window² will not accept drag&drop. Drag&drop dead zone also grows vertically from the top of the window, and depends on how far from the top of the monitors the window is. If I were to quarter-tile GIMP, et al window in the right-bottom corner of my left (150%) display, the window would accept drag&drop only in the bottom-right corner of the window. [1] Half of the window being a quarter of monitor resolution, or ~(scaling_factor - 1) * window_x_position [2] Quarter of the window being 1/8th of monitor resolution, or ~(scaling_factor - 1) * window_x_position OTHER SOFTWARE: This problem does NOT happen with Firefox, Chrome, LibreOffice Writer, Dolphin, or GIMP 2.99 (gimp-devel-noconflict from AUR). Drag&Drop also does not work for Darktable, but drag&drop behaviour in Darktable is inconsistent with this bug (drag&drop doesn't work at all).
