QGIS stuck reloading loop

[qgib]

Author Name: David Jordan (David Jordan)
Original Redmine Issue: 17473
Affected QGIS version: master
Redmine category:rasters

---

I have Lidar topography of Mount Shasta in QGIS; topography, hillshade and a slope map (all in EPSG 3488 projection).

After updating to the latest nightly (2.99.00-215) I zoomed into the map and now QGIS stuck loading and reloading the rasters in an endless loop. I can see disk I/O activity which confirms that QGIS is reading the rasters over and over again. Turning of rendering stops this behavior but the blue progress bar continues to cycle. I opened another project using same rasters and the the loop happens again.

Hi Giovanni,

Here's my project file and raster data, the file is rather large so I shared it via dropbox. The issue is repeatable after opening the project, by choosing "zoom to layer" in the layers panel and then zooming in using the magnifier. The layers then continuously load in a loop.

Just tested on the latests master (osgeo4w) and can't replicate.

I deactivated plugins one by one and I found that the plugin "Load QSS - UI themes" caused the issue. It wasn't QGIS. It's a pity, I liked the Dark theme it provided.

David, report the issue to the plugin author and you'll have more chance to reuse it in a cleaner environment soon.
