Troubleshooting

• "Would create a cyclic reference" — you tried to place an instance that would eventually contain itself. Restructure: flatten one branch, or place the array inside a different cell.
• Nothing draws when I click — the active layer may be hidden or locked, or you're inside a cell you did not mean to be in (check the breadcrumb).
• Ctrl + 0 jumps to a tiny corner — you have something selected far from the main content. Press Escape first to clear selection, then fit.
• Paste lands far from the cursor — Ctrl + V uses the cursor's world position as the anchor; move the cursor into the canvas before pressing it. If you want the content back at the exact coordinates it was copied from instead (e.g. reproducing a layout in another tab), use Ctrl + Shift + V ("Paste in place", Tabs) rather than fighting the cursor-anchored placement.
• A shape I drew isn't in the exported .gds — it's probably flagged "For construction" (dotted outline). Toggle the flag off in the Properties panel. Bitmaps are also intentionally excluded — trace them first (Bitmap import & Trace).
• My colleague's other tool doesn't show my font — Glyph embeds the font inside the .gds (a private __GLYPH_FONTS__ cell) and reads it back when Glyph re-opens the file, but tools like KLayout / Clewin ignore that cell, so they do not draw the text in your font. Flatten the text first (Fonts) so the glyphs become real polygons that every tool draws.
• The Claude pill won't go green — the MCP server probably isn't running. Click the pill → "First time? Open setup guide" and run the installer; the pill turns green automatically once the server is up and the token matches.
• A grey "Software rendering" chip sits in the status bar (it reads "CPU" on a narrow window) — your browser's GPU driver isn't available, so Glyph is drawing with a CPU fallback; pan/zoom will be slower on large files, especially dense hatched layers. A one-time notice explains this the first time it's detected; the chip stays as a permanent reminder afterwards.
• The canvas is blank but the file has geometry — everything in the active cell is outside the current view. The status bar's count then reads … · none in view — Zoom to fit (shortened to None in view — Zoom to fit, Off view — Fit or Fit on a narrow window); click it to bring everything back. A shape you commit by typing (a Box corner, a polygon or path finished with Enter, a Text, a Properties W/H edit, a paste) that lands entirely off-screen offers a Zoom to fit toast rather than jumping the view for you (it goes away by itself once any part of the shape is in view) — the toast does not take the keyboard, so Enter keeps drawing (reach its action by Tab, the mouse, or Ctrl+0) (only the very first shape drawn into an empty cell is framed automatically).
• Several messages fired at once and some seem to have vanished — the toast stack shows at most three at a time; the rest collapse into a "+N more — View all" row (repeated identical messages count instead of repeating, e.g. "(×10)"). Click it to see everything that was reported.
