Flicker #2

Closed bpranoto closed 3 months ago

bpranoto commented 6 months ago

Application flickers badly when running remotely.

To show the problem, I created a simple app with just one form and nothing else which can be download from https://drive.google.com/file/d/1ZrMzhPauAhiwV4UMVMxWOW6HPOP1P7pe/view?usp=sharing

Then from windows station, I connect to the linux host through putty and run the application.

After the application form displayed, the application flicker badly whenever I resize the form.

Here is the youtube video of the problem described above: https://www.youtube.com/watch?v=daheodHgNhc

The application is created with Lazarus 3.1/FreePascal v 3.2.2

Should be fixed in release 21.1.13

Strange, because I do not see this problem anymore. I am running your program from wsl in windows 11. With the previous version, I saw the problem you described.

Yes, it is much better.

It still happens occasionally. As it is an intermittent issue, and I cannot always reproduce it, I deleted my last message in the github.

The problem is more apparent if I run the program through X2go which uses vcxsrv as X server. However, I don't know if it's more related to x2go client or vcxsrv

I am able to reproduce easily when running your program from a linux pc. Could you share me the source of this program? I do not see the problem with other X clients (kdiff3, xterm, ...) Maybe that it could help me in finding out the real cause of this problem.

Here it is. Actually, it is just a do nothing template application.

The application is build with Lazarus v3 and Freepascal 3.2.2 under linux. If you don't have lazarus/freepascal in your system, I recommend to install with fpcupdeluxe https://github.com/newpascal/fpcupdeluxe/releases/latest.

The problem is not there if it is compiled with Lazarus version 2.

Thank you very much.
