Here are the starting times of
- UEStudio v17.20.0.15 with default settings,
- but with using toolbar/menu mode with traditional menus,
- and opening a project with 34 *.cpp and *.h files
- which are additionally opened all on startup,
- on a Dell E6500 with Intel Core Duo T9600 2.80 GHz with 4 GB RAM and a Samsung SSD 850 EVO 1 TB hard disk
- using Windows 7 SP1 with Windows Classic desktop theme additionally customized to avoid any color fading and shading effects (active/inactive window title bar have only one color) and visual effects configured for best performance,
- and no anti-virus application or other application running in background which could result in a longer startup time.
Not dockable file tabs:
- 1st startup time: 4.9009807 s
- 2nd startup time: 5.4801985 s
- 3rd startup time: 4.0505038 s
Average startup time: 4.8105610 s
Dockable file tabs:
- 1st startup time: 6.3292320 s
- 2nd startup time: 6.5398676 s
- 3rd startup time: 7.2077388 s
Average startup time: 6.6922795 s
So average startup time with not dockable file tabs is 71.88 % of average startup time with dockable file tabs respectively average startup time with dockable file tabs is 139.12 % of average startup time with not dockable file tabs.
The startup times are measured with Process Monitor with a filter to display only
uestudio.exe file system activities. The total startup time is simply the time of last log entry minus time of first log entry after switching from UEStudio to Process Monitor after UEStudio start. Please note that I wanted with those measurements not find out how long UEStudio really needs to start and therefore if the last log entries are really from UEStudio start and not a cause of switching from UEStudio to Process Monitor. I just wanted to know if using not dockable tabs (default) is really faster than using dockable tabs like when having
Enable tiling/dockable tabs activated. I have not looked on what was recorded by Process Monitor. I have just subtracted time of first line from time of last line.
Conclusion: Using dockable file tabs makes starting UEStudio with lots of files to open on startup slower, but definitely not 10 times slower.
I could not reproduce any issue with quick tips display on using dockable file tabs with the opened *.cpp and *.h files being ANSI encoded. Perhaps there is one more setting responsible for quick tips not working as expected. I suppose a setting which cause a window refresh on your computer with your configuration not occurring on my computer with my configuration according to what I could see on your video.
I suggest to compress into a ZIP or RAR file the entire UEStudio application data folder and the project folder with the *.prj and *.pui file and all the project files. Next send an issue report email to IDM support with that ZIP/RAR file attached to IDM support and explain step by step how to reproduce the issue with quick tips on using your configuration and your project. Please add also all hardware details and the Windows desktop configuration as done by me here because that could be also a possible source for the different behavior.
