Some Gomboc windows do not display correctly on my machine. Panels that should show
interactive content appear blank, partially rendered, or otherwise broken. Other parts of
the application seem to work normally, for example the Foil Editor window.
The machine is capable (recent CPU, dedicated GPU) and meets the usual hardware requirements. What can I try?
Edoardo Asked question
Several Gomboc windows use an embedded HTML view (Qt WebEngine). On some systems — in
particular with newer GPUs or certain graphics driver configurations — these views may fail
to render correctly even though the rest of Gomboc runs fine.
Try the steps below in order.
1. Check graphics driver and GPU selection
Make sure your graphics drivers are up to date.
On laptops with both integrated and dedicated graphics, confirm that Gomboc is set to use the
high-performance GPU (for example NVIDIA) rather than the power-saving integrated GPU. See
the *Graphic Card* section in the Gomboc installation guide.
2. Disable GPU acceleration for Qt WebEngine
Create a batch file in the same folder as `Gomboc.exe` with the following content:
@echo off set QTWEBENGINE_CHROMIUM_FLAGS=--disable-gpu --disable-gpu-compositing start "" "Gomboc.exe"
Run Gomboc through this batch file instead of double-clicking the executable directly.
3. Force software rendering for Qt Quick
If step 2 does not fix the problem, try forcing software rendering for Qt Quick:
@echo off set QT_QUICK_BACKEND=software start "" "Gomboc.exe"
Note: software rendering may reduce interface responsiveness compared with GPU rendering.
Use it as a workaround rather than a permanent setting unless needed.
4. Contact us
If none of the above resolves the issue, please share:
- Gomboc version
- Windows version
- GPU model and driver version
- Screenshots of the affected windows
A short screen-sharing session is often the fastest way to identify the cause when the
problem is machine-specific.
