Troubleshooting

I closed the app without saving

Open Illusion again — it offers to recover your autosaved work. You can also look in File → Version History / Auto-Backups… for the rolling backups.

My hand or finger leaves marks on the tablet

Turn on pen only: the hand / pen button in Simple Mode, or untick View → Allow Finger Drawing & Selection. See S-Pen, touch & gestures.

I can't move an object

  • It may be locked — check the lock icon in the Layers panel, or its whole layer may be locked.
  • You may be grabbing the pivot in the middle of the selection; grab the object elsewhere.
  • In isolation mode, objects outside the isolated group can't be selected — press Esc.

Strokes come out without pressure

Pressure needs a stylus. With a mouse or finger, strokes use a simulated taper. Check Pressure Sensitivity in the Brush settings isn't at its lowest.

A PDF won't open as an editable document

Only PDFs exported from Illusion with Keep editable in Illusion turned on carry the document inside. Other PDFs can't be opened for editing yet — use Import / Place Image for pictures, or ask for an SVG.

A font looks different on another computer

Fonts aren't embedded in SVG files. Use Text → Create Outlines before sharing, or export PDF (fonts embedded, or text as outlines with Selectable text off) or Print (SVG), which turns text into outlines.

Drawing feels slow

  • Hide layers you aren't working on.
  • Very large images slow everything down — crop them, or rasterize them to the size they are shown at.
  • A sketch with hundreds of brush strokes gets heavy. Select it and rasterize it into one image.
  • Outline mode (Ctrl Y) is fastest for arranging complex documents.

The Linux window is blank or flickers

Illusion on Linux draws with your graphics card. If the window stays blank, flickers or shows garbage, start it with GPU drawing off — slower on big drawings, but it works everywhere:

WEBKIT_DISABLE_DMABUF_RENDERER=1 illusion

On computers where NVIDIA's own driver runs the screen, Illusion already does this by itself.

Still stuck?

Write to vladimir@illusion.quest or use About → Report Bug / Feedback… in the app. Include your platform (web, Linux, Android) and, if you can, the .illu file.
