[Bug] "Out of memory" exception after migration to 6.99.14.3

[Regis]

After switch to RenPy 6.99.14.3.3347 one of game developers started to get regular "Out of memory" exceptions.

• Rollback to RenPy 6.99.13 resolves the problem.
• The issue does not reproduce for everybody. I can't reproduce the issue (I use Windows 7, 64 bit). The developer that gets the issue has Windows 10 (RenPy says that it's WIn8) and 128GB RAM.
• The issue appears very close to game start. Usually after few interactions with tooltips (old style).

Any ideas how we can debug the cause?

Traceback:
I'm sorry, but an uncaught exception occurred.

Upd: the issue is reproducible by at least 2 users. All have Windows 10.

Interesting, someone else had the same problem previously, not sure if related:

Although they were using a bitmap - but png are also raster graphics so I wonder if it's a similar issue? Perhaps open and resave it in your image editor to see if issue continues?
