Blank pop-ups in Power Query aren't a minor inconvenience. They're a hard stop. When a merge dialog or delete confirmation opens as a white void, the user isn't just slowed down, they're locked out. The person who posted this question on Reddit, angelinament, is describing a failure that turns a productivity tool into a source of frustration. Our take is straightforward: this problem is unacceptable, and the way it gets solved matters.
The root cause is almost certainly a graphics driver conflict or a display scaling issue, not a bug in the query logic itself. That's cold comfort when you're staring at a blank screen. Workarounds exist, disabling hardware acceleration in Excel's options, updating your graphics driver, or adjusting Windows display settings, but they shouldn't be required just to see basic dialog boxes. A spreadsheet tool that hides its own interface has broken the fundamental contract of usability. The real lesson here is about design philosophy. Power Query is powerful, but its complexity can create friction points that alienate the very users it aims to empower.
What this means for you is practical. If you encounter this blank-screen problem, try the fix first: go to File > Options > Advanced, scroll to the Display section, and uncheck "Disable hardware graphics acceleration." Restart Excel. That resolves the issue for most people. If it doesn't, check your Windows display scaling, set it to 100% temporarily to see if the pop-ups reappear. These steps are not a permanent solution, but they get you moving again. The deeper point is that no one should have to become a display driver expert to merge two data tables.
We believe the future of data management should remove these barriers, not add new ones. An AI-native spreadsheet that understands what you're trying to do can handle merge conflicts or query deletions without ever presenting a blank dialog. The technology exists to make these interactions conversational, you describe what you want, the tool executes, and the pop-up never appears. That's the direction worth exploring. For now, if you're stuck with a white screen, apply the hardware acceleration fix. Then consider whether a tool that requires that fix is still the right one for your workflow.
