same issue on my end.  would be nice for miro to publish fix.

Happening for me too - only a recent event of the last few months.   Uploading pdf’s and ppt’s before then viewed perfectly.  Now it’s the same grainy twinkling in and out as the above images.

I am having the same issue with an imported pdf. Unreadable. Zooming in and out doesn’t do anything. Reloading the board does nothing. I’ve sent a support request to Miro. But I can’t believe this issue already persists for three years!!!! I am on a payed plan so extra frustrating.

Hello! I need help in exporting one board from an upgraded member. I am not having fund to upgrade but worked on a board extensively to visualize my youth work. It is a non-profit youth work related research and any help in exporting in high quality will be greatly appreciated and I shall be ever thankful to you for this. Please help me as the board concludes my 7 years of work. 

Here is the board: 

I’m having the same issue here as of yesterday. Blurry PDF’s that also make the navigation on Miro board jagged and jumpy, smooth zoom and pan is lost. If I delete the PDF it reverts to smooth navigation again. Perhaps another post about this. 

I thought it was at the Software Authoring the PDF (ArchiCAD) but other pdf’s from there are fine. I tried the Open in Preview export as PDF option too to re-author it but this same pdf still gives issues. 

May try PDF to SVG vector as workaround in InkScape. 

Users on i pad are reporting same problem here also.

I’m also having blurry images on MacBook Pro, using the app. Makes Miro quite unusable :(

You can try upload as jpg, png or screenshots copy see if it works. 

It seems this is a recent problem. Two months back, I could infinitely zoom into a vectorized pdf or svg without any issues.

Same problem. I don’t know if this is solved elsewhere, but would be great to include a solution on this thread which is the first google hit for this issue.

… The issue of blurriness when pasting Powerpoint slides persists (for me at least). 

Has anyone found a solution besides pasting from PDF versions?

OK, after quite a bit of fiddling, I have determined that the workaround is to zoom the __ in - like to see only 1/4th of the slide in my full window, and it will then properly resolve/load up.  At least now I know what to tell the clients if they can’t read the slides.

@Miro, the issue is that if I load up a board and it includes PDFs that take up a portion of the window, Miro is set to only serve up a low res - FPO? image, requiring me to zoom in WAY too much in order to get the full resolution to load up.  

I understand the idea of serving up only what is needed, but these - break points? are set completely wrong for me.  Let’s please remember we all now have high speed internet - this seems set at “Mid 90s DSL internet as seen on a VGA display” when I have Gig and a 4k.  Literally not serving them up so they can be read (until after zooming in, then fine).  This should be enough to make it very clear what the issue is, and I would be happy to provide any other information in order to make this “real” for Miro’s support and thus get this into the pipeline for a fix.
