Bug ID: 510807
Summary: Dragging layers with touchscreen or drawing pen causes
soft lock
Classification: Applications
Product: krita
Version First 5.2.13
Reported In:
Platform: Flatpak
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: Usability
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
If you attempt to drag a layer with the touchscreen or drawing pen to
re-organize it, the app will lock up. It hasn't frozen or crashed, but it stops
responding to user input. You need to spam the escape key repeatedly and left
click your mouse to get the program to unlock.
This bug is 100% reproducible, and occurs each and every time a user drags a
layer using their finger or stylus. It does not lock up if you drag the layers
using a mouse. This bug is very severe as it also interferes with normal system
input, such as being unable to click outside of the main Krita window.
This causes a massive disruption to almost any workflow involving multiple
layers and heavy use of a tablet. For 2-in-1 users such as my girlfriend, this
is especially frustrating. She has a Lenovo X1 Yoga Gen 6, and she prefers to
draw in tablet mode. Every time she accidentally touches a layer, she needs to
unfold the laptop and spam the escape key, and then fold it up again. This is
very frustrating and inconvenient. As a non-technical user, it may have taken
her a long time to discover a workaround had I not been there to troubleshoot
the issue with her. This presents a major usability issue for new users, and a
major workflow issue for experienced users, especially when you consider this
locks up the entire system, causing the whole desktop to stop responding to
mouse and touch input.
STEPS TO REPRODUCE
1. Open Krita on a touch-enabled device (preferably one with a
pressure-sensitive drawing tablet attached)
2. Create a new document
3. Create a new layer
4. Attempt to drag the layer using the touch screen or drawing tablet
OBSERVED RESULT
• User input instantly locks up. Layer appears to be hovering, as if it is
being held still by the user.
• Operating system does not respond to touch events, cursor replaced with
floating layer widget, computer appears to be completely frozen.
• Attempting to move the mouse makes the layer move with the mouse, but you
cannot left click to drop the layer.
• Only way out of this soft lock is to hit escape key a few times and click the
mouse.
EXPECTED RESULT
Layer drag and drop should work for touchscreens and tablets, or be disabled.
SOFTWARE/OS VERSIONS
