Form flicker with sparta_dockedformeditor in 1.8RC4
« on: August 26, 2017, 10:55:38 am »
Hi,
Just install lazarus 1.8RC4 on win10 64bit and start to test it a couple of days ago. I always use anchordocking + spartadockedformeditor on my IDE.
Why sparta in this release (compared to release in laz 1.6.4) when I click an empty form in designer/form view, the right side of the form is always flickered and moving components in the form is not as smooth as using sparta in laz 1.6.4?
This is really obvious when I run it in my notebook with intel celeron processor. Also, when I open my projects that has many components, the TListBox or virtualstringtree in my form become flickering too when I click other component (like button or tedit) or the form.
Strangely, the flickering components does not happened in all forms. In the mean time I'm unable to give how to reproduce this since there is quite a lot of components in my forms and maybe related to their aligning. Currently, I uninstall sparta from laz 1.8RC4 and use sparta from laz 1.6.4 package.

You may need an upgrade of FPC as well. What is your FPC version? (I can't reproduce this with 1.9/3.11 from today. It is reproducible with 2.6.4 which is no longer supported)
[edit] it is also reproducible with 3.0.0 but not with 3.0.4

Specialize a type, not a var.

I use 1.8RC4 with FPC3.0.4RC1. Do you mean this is related to fpc version, not the sparta itself?

Follow the commits in trunk. I am using Laz 1.9-r55743 and FPC3.1.1-37058 at the moment.
There have been a few (  ;D ) commits regarding this issue.....
