SUMMARY When attempting to use Dolphin with a Wacom tablet, the majority of the interface (files, folders, sidebar) is impossible to interact with. * No matter if Wayland or XWayland * Doesn't work with normal folder/files * Doesn't work with sidebar folders * Interaction with buttons and text fields work * Works on Nautilus flatpak, no matter if Wayland or XWayland * Works on Kdialog STEPS TO REPRODUCE 1. Login to a Plasma Wayland session 2. Open Dolphin 3. Try clicking or selecting files on Dolphin OBSERVED RESULT Impossible to interact with files and folders EXPECTED RESULT Normal interaction with files and folders SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20200823 (build from 2020-09-14) KDE Plasma Version: 5.19.80 KDE Frameworks Version: 5.75.0 Qt Version: 5.15.1 Kernel Version: 5.8.0-1-default OS Type: 64-bit Processors: 4 × Intel® Core™ i5-7200U CPU @ 2.50GHz Memory: 15.5 GiB of RAM Graphics Processor: Mesa DRI Intel® HD Graphics 620 ADDITIONAL INFORMATION Wacom Tablet: Intuos CTL480 Pen Small Properly recognized via libinput list-devices Device: Wacom Intuos S Pad Kernel: /dev/input/event2 Group: 6 Seat: seat0, default Capabilities: tablet-pad Tap-to-click: n/a Tap-and-drag: n/a Tap drag lock: n/a Left-handed: n/a Nat.scrolling: n/a Middle emulation: n/a Calibration: n/a Scroll methods: none Click methods: none Disable-w-typing: n/a Accel profiles: n/a Rotation: n/a Device: Wacom Intuos S Pen Kernel: /dev/input/event1 Group: 6 Seat: seat0, default Size: 152x95mm Capabilities: tablet Tap-to-click: n/a Tap-and-drag: n/a Tap drag lock: n/a Left-handed: n/a Nat.scrolling: n/a Middle emulation: n/a Calibration: n/a Scroll methods: none Click methods: none Disable-w-typing: n/a Accel profiles: none Rotation: n/a
You say "doesn't matter if wayland or xwayland" how does it react in X?
Oh, that's true, my mistake (I was testing and noting on Kate). It's the only of the five bugs that behaves the same in X.
In that case it's a dolphin bug - I guess QGraphicsView doesn't have the synthetesised event handling.
I wonder if it works now that touch support was just added to Dolphin. That happened yesterday, so maybe you were using an older build?

Hello, I updated just now. The reported lack of interaction still exists, and now I have additional behavior: long press with the pen (I mean stylus btw) allows me to select a file/folder, and clicking elsewhere opens the context menu to move or copy it. Long pressing does the same. Oddly enough, it only happens with the first file you long press. Any subsequent attempts simply call the context menu for the same file. Long pressing other files results in the same thing.
