Using react-pdf, we crafted a solution that allowed users to manipulate their reports with an impressive degree of flexibility. But, as data grew (imagine trying to cram an entire financial year's worth of invoices, up to 22,000 rows, into one PDF), our solution began to falter, especially on older PCs with limited resources.

Do you mind reporting those issues either to SumatraPDF at https://github.com/sumatrapdfreader/sumatrapdf/issues or directly to MuPDF at https://bugs.ghostscript.com/ if it also has the same issue? Thank you!
There are many wonderfully weird PDFs and epubs out there, but we do our best to fix issues. :)

Project mention: Intro to DOMPDF - lightest and simplest PHP library to generate PDF documents | dev.to | 2024-04-05
Generating PDF documents out of your app's HTML output is a very common requirement and there are several open source libraries to accomplish this. I came across this need for my project recently and I evaluated many popular ones such as TCPDF, mpdf, FPDF, etc. But the one that truly stood up to my evaluation in terms of efficiency (minimal footprint) and ease of implementation was DOMPDF.

xournalpp
Xournal++ is a handwriting notetaking software with PDF annotation support. Written in C++ with GTK3, supporting Linux (e.g. Ubuntu, Debian, Arch, SUSE), macOS and Windows 10. Supports pen input from devices such as Wacom Tablets.
Project mention: Rnote – An open-source vector-based drawing app | news.ycombinator.com | 2024-03-11I highly recommend Rnote to anyone on Linux that misses the "hodgepodge" notetaking of apps like OneNote. It works like a dream on touchscreens and drawing tablets, with a surprising amount of configuration under the hood.
Also worth noting is Xournal, an older but similar project: https://xournalpp.github.io/
