Welcome to TVPaint Community forums !

I created a dedicated topic to this problem (bug found by Skomdra).
Screenshots and details about the config and TVPaint version should arrive soon and the topic will be opened just after. (done)

Config :
TV Paint 11.0.3-64 bits ; iMac (Retina 5K, 27-inch, Late 2014) ; OSX 10.10.5 ; AMD Radeon R9 M295X 4096 MB; Wacom Driver version: 6.3.15-3
It also happens on 11.0.3-32 bits.

Video :

On the 64bit version of TVPaint 11.0.3 the brush lags on heavy zoom. If you zoom more the lag becomes more apparent.
THIS VIDEO shows the lag with only one layer, if I add a few more layers the lag becomes heavier pretty fast. I compared it to the 32bit version, but noticed no lag there.

EDIT:
OS X 10.10.5 / 3,5 GHz Intel Core i7 / 32 GB MHz RAM / NVIDIA GeForce GTX TITAN 6144 MB

Thanks. As we are not 100% sure everyone has the same issue, I prefer to keep everything separated at the moment.
Don't forget to add your config infos.

Schwarzgrau, I have the same issue than you with my Retina Screen, Mac OS 10.11.4, 64 bit (TVPaint 11.0.3 Beta).
I don't have this issue when using the 32 bit.

However, I must zoom A LOT to have it.

Yea, I must zoom a lot too, but unfortunately there are a lot of situations where I need to zoom a lot, since I'm trying to work really accurate.

Please,
can you make the test once with the mouse and an other time with the stylus on both 64 and 32 bits ?

There seems to be no lag at all, if I use the mouse (in both versions). With the stylus I only get it on the 64bit version.

You're using the official 10.0.3 or the beta version that Fabrice sent you ?

Fabrice didn't sent me a beta version, so I'm using the official build.

I have the same issue when using a tablet, both on 64 and 32 bit.
The issue is only in 64 bit when using a mouse.

Are you sure you don't experience the lag when you zoom a lot in a 32 bit + using the stylus ? It's visible especially if you draw waves and if your window is maximized (if you make it small, you won't have any issue).

Sorry you're right, it happens in the 32bit version too. I didn't zoomed enough.

Phew, I prefer that (it's always easier to fix an issue that behaves the same everywhere ! )

ok, good to know !

I have merged Skomdra and Shwargrau's topics, since both issues are the same (they appear to be, at least)
