Hi, When I click in a tab editor blinks but not using Ctrl+TAB.
What blinks?
Lazarus 1.1 r41446 FPC 2.6.2 i386-win32-win32/win64

I've seen this before too... The whole editor window blinks. eg: I have a dark (black) text editor theme. Sometimes I used to see the editor first paint white, then my dark theme - giving the blink effect when changing tabs.
Though I haven't seen this happen in a while.

I take that back... It still does it (under FreeBSD and Windows), I just got so used to it that I didn't really notice. Here the blink effect happens, irrespective of how I change editor tabs (keyboard or mouse).

What blinks?
The same that Graeme said, ie, the whole editor window blinks. I use a dark (black) text editor theme too.

Mattias,
Did you reproduced the problem?

Mattias,

No.
I guess it happens only on some Window managers.

Afaik in is a windows w32/w64 issue.
IIRC there was something about the TPage doing an erase-background. But I may remember that wrong.

Nope, I'm running FreeBSD 9.1 now, and before I ran Ubuntu 12.04 - both systems showed this problem.

Mattias Gaertner wroteI guess it happens only on some Window managers.
It happens here under stock Gnome 2 desktop environment, and under JWM (Joe's Window Manager).
What is even more strange is that if I have a few tabs open, say 8 tabs in the editor. The "white flash" occurs with every tab change, except when I go from the 5th tab back to the 4th tab. This is reproducible with 5+ tabs, even after a Lazarus IDE restart and even reproducible between window manager switches (eg: Gnome 2 DE -> JWM or back).
So what makes tabs 4 & 5 special? I can video this if you wanted to see.

I could see a blink of synedits right column on some page changes. It is reproducible as long as the IDE is running. After a restart it was gone.
I found a suspicious gtk2 draw call and disabled it. Please test with 41658.

It's better... ie: not every tab switch causes the white flash. But switching between some times, and depending on direction of tab switch, it still flashes white. I'm trying to find a pattern. So far if a tab causes a flash, it is always that tab, an then the opposite is true too.
[...few minutes of playing with IDE...]
OK, if my project session is saved with 8 tabs open, and I restart the IDE and my previous opened tabs are loaded... no white flashes occur switch between any or those 8 tabs. This is an improvement to how it was before. If I now open new tabs by clicking on the Project Inspector or on the listed files in a Package, and then switching to or from those newly opened files, will cause the white flashing again. It will also introduce one or two white flashes between the existing 8 open tabs I had. Say I now have 15 open tabs. Now if I save my project (with info of opened files), and the restart the IDE. Now all 15 tabs will not cause a white flash. Opening new files or closing any tabs, will randomly start the white flashing again.
I wish I can "unlike" Marco Douglas's original message. :) Since he mentioned it, I now notice the damn white flashes again! :-/

Works on WinXP (I still have not updated). I will update and test on Win7~8.

No, only gtk2. I can't help you on Windows.

It seems to be fixed now (tested LCL-GTK2 only). Thanks Mattias.
I now found that Lazarus Trunk crashes every time on opening a specific file in fpGUI, but that is unrelated to this blink issue. I'll file a bug report for the crash.
