Hi! I launched it on Fedora with Wayland and unfortunately couldn't reproduce the issue myself. The issue is probably caused by this bug in Tauri (a library Calligro uses).
Would you mind trying to launch Calligro with the following environmental variables set?
- WEBKIT_DISABLE_DMABUF_RENDERER=1
- WEBKIT_DISABLE_COMPOSITING_MODE=1
In other words launch it using this command:
WEBKIT_DISABLE_DMABUF_RENDERER=1 WEBKIT_DISABLE_COMPOSITING_MODE=1 ./Calligro
Let me know if that helped
