Steps to reproduce:
1. In the new canvas create note with 16 font size text:
Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.

2. Near this note create 3 notes with 16 font size text "Lorem ipsum", and increase their width to the width of the first note. Like this - https://imgur.com/a/DyEaddg

3. Copy all 4 notes and start spamming Ctrl+V, quickly zooming in and zooming out camera from texts. Approximately after 10 seconds, the font of notes become distorted.

This is the easiest way to reproduce this bug. Usually it emerges not during copypaste of notes, but after a short time of work with a canvas which contain many texts.

Distortion effects disappear after PureRef restart. Only to reappear after a few minutes of work.

This bug potentially could be related to a similar bug - during work with note which contain a lot of text, some recently created text suddenly visually disappear. And begin to be displayed again only after change of note size. Probability of such disappearing correlate with number of colorful texts and bullet lists in one note.

Thank you very much for the detailed report! We managed to figure out what's going wrong using your repro steps and will make sure to have it fixed in the upcoming version of PureRef. We're not sure if the second issue you mention is the same issue but let us know if you manage to figure out a repro case for that and we will test and verify.

Thanks to you too! Eagerly look forward to next version, and I sincerely hope that it will have tabs.

Steps to reproduce second bug:
1. Create note with big text.
2. Open few sites with heavily formatting texts.
3. Copy random texts from sites to random parts of note.

After some time, the copied text will disappear, and keyboard typed text will become invisible. Until change of note size, or note copy-pasting.
This bug also happens if begin to copy different formatting text from one note to another. But less frequently.

Also, perhaps it's related, the more canvas have unicode emojis - the slowly and glitchy it becomes.

The first issue should be fixed now in 2.0.1, please let us know if it helped for the second one as well!

This solved two bugs but resulted in bigger memory usage.

The same canvases in full view and with Cache on disk setting:

PureRef 2.0.0.beta8:
New canvas with 105kb of text - 45mb memory.
Canvas 1, with many texts - 791mb memory.
Canvas 2, with many texts - 967mb.
Canvas 3, few texts - 345mb.

PureRef 2.0.2:
New canvas with 105kb of text - 606mb memory.
Canvas 1 - 4,832mb memory.
Canvas 2 - 5,566mb.
Canvas 3 - 670mb.

> please let us know if it helped for the second one as well!
> No, the bug remains. Try to create a large number of bullet points with texts of different colors. And spam by random pieces of texts to random places. Soon parts of the text will begin to disappear.

Sorry for the long wait, but we think this is now fixed properly in the new beta version of PureRef 2.1.0. If you give it a try, let us know if it helps!
