What causes a crash when minimized?

Minimizing can reduce the window to zero size or release the graphics device, and rendering code that creates a zero-size buffer or uses a released device crashes on minimize or restore.

How do I catch this when it only happens for some players?

Capture it automatically from the player's device with the full stack trace, the device and OS, the build, and a breadcrumb trail of what they did. That turns a vague complaint into a specific, reproducible issue you can fix without owning the hardware it happens on.

How to Fix a Game That Crashes When Minimized

Quick answer: Skip rendering while minimized, guard against zero-size render targets, and recreate the graphics device and swap chain on restore.

A crash on minimize is rendering into a zero-size or released surface. Handling the minimized state fixes it. Here is how.

How to fix it

1. Skip rendering while minimized

A minimized window can have zero dimensions. Detect the minimized state and skip rendering (and resizing render targets) until it is restored, so you never create a zero-size buffer.

2. Guard zero-size render targets

Creating a render target or swap chain with zero width or height fails or crashes. Clamp to a minimum size or skip the operation when the window is zero-sized.

3. Recreate on restore

Minimizing in some modes releases the device or swap chain. On restore, recreate them and the render targets at the new size before resuming rendering, rather than using released resources.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every your game error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.

Reproduce it once with full context and the fix writes itself. The hunt is the expensive part.
