performance issues and crash warnings with 2.3 (final)

[ungutknut 4]

Hi,

since the final version of 2.3 the performance when moving the camera around is pretty bad. This wasn't the case with 2.1 and 2.3 beta. Anyone else experiencing this issue?

Perhaps hardware acceleration isn't working anymore?

specs:

i5 3470

16gb ram

ssd

gtx970 (with latest nvidia driver provided by my packet manager)

Xubuntu 16.04 64bit

There's another minor issue that persists since 2.1 I'd like to mention:

Whenever I close cura, a few minutes after closing an error message will appear saying that cura has crashed (wich isn't the case - I've closed it on purpose) and asking me if I want to submit a log file.

Is this a known issue? If not I'll start a new thread for it and add the log to my report.
