Bug ID: 515623
Summary: Cannot switch back and interact with canvas for many
canvases after switching to another canvas tab
Classification: Applications
Product: krita
Version First nightly build (please specify the git hash!)
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: General
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
Krita 5.4.0 prealpha @6685687bd6, also present on 5.3.0 beta (both AppImage).
Multi-canvas usage is incredibly broken, with canvases no longer becoming
editable after switching away, but triggering the breakage is a bit random.
STEPS TO REPRODUCE
1. Open a large canvas (mine was 2.7G, at around 10k x 7k pixels
2. Open a second canvas. (can be a backup, newer version, or a png, or blank
canvas)
3. Switch away from the affected canvas (via tab bar)
4. Switch back, and attempt to paint or pan/zoom the canvas
4b. Alternatively, try to toggle visibility of a layer and mouse back over the
canvas.
It seems like it affects the save files randomly.
OBSERVED RESULT
Using tools switches the canvas back to another tab (with three tabs, it seems
to switch back to the same tab regardless of tab order or visit order).
Attempting to pan or zoom does nothing. On Wayland, the cursor is not visible
over the canvas. Toggling a layer visibility seems to work, but mousing back to
the canvas warps back to another canvas.
EXPECTED RESULT
I should be able to switch to another canvas freely (to e.g. colorpick) and
switch back without worry of the canvas being no longer paintable or
navigatable.
SOFTWARE/OS VERSIONS
KDE Plasma Version: 6.5.5
KDE Frameworks Version: 6.22.0
Qt Version: 6.10.2/5.15.18
Kernel Version: 6.18.7-arch1-1 (64-bit)
Graphics Platform: Wayland
(I also replicated this on X11/MATE on another system with the beta)
ADDITIONAL INFORMATION
(trying the qt6 appimage version locked up on F4, and the qt6 git version had
an uninteractable UI, so cannot test those)
