<ul><li><strong>Status</strong> changed from <i>Open</i> to <i>Feedback</i></li></ul><p>Can you share share a test project and data to reproduce this issue?</p> QGIS Application - Bug report #21776: rendering cycles forever when viewing raster at certain scaleshttps://issues.qgis.org/issues/21776?journal_id=1037142019-04-05T14:37:50ZTony Walterstony.walters@i-valley.ca
<ul><li><strong>Status</strong> changed from <i>Feedback</i> to <i>Open</i></li></ul><p>The project where this behaviour occurs is very large - many GB. I created a small project with one of the LiDAR rasters that were exhibiting the behaviour. Unfortunately, the problem does not occur on that. I attach the link to the files anyway.</p>
<p>As a note, the problems does seem to be worse when there are many layers. Is it possible that with many layers the system has to continuously iterate across the layers? Should there be an index on the layers or some mechanism to make that a lightweight function?</p>
<p>It will be hard to de-compose the main project incrementally to see where the problem goes away (if it does).<br />Any other suggestions on how I can assist debugging this?</p>

<p>linking (even privately if contains non shareble data) the large project and data would help.</p>
