#528 Titus The Fox game characters vibrate

[Mohammed Sayed]

I use the latest SVN build of DOSBox (r4337) with D-Fend Reloaded frontend.
I set the Window resolution and Fullscreen resolution to Original.
I start with Fullscreen.
I also use Double Buffering.
My render is Surface.
My Video card is set to vgaonly. No scaling and 0 frameskip.
My emulation core is set to dynamic.
My CPU Type is Auto.
My CPU cycles is Auto.

When I play "Titus The Fox" in the first level, sometimes some characters (including the Fox) disappear and reappear very quickly (vibrate). Only clear in the end of the level.

Is this a bug?
Please investigate and tell me.
Please try to fix if it is a bug.
Thank you very much.

Which cycles count are you using with the game ?

[Qbix]

I meant what is displayed in the top bar ?

[Mohammed Sayed]

I use Fullscreen.
But when I switch to windowed mode, the cycles are 3000 cycles.

[Qbix]

does it change if you change that number to higher number (like 10000) ?

cpu cycles change the auto to 10000

[Mohammed Sayed]

Yes, it runs fine. But in such speed, the sound changes from MIDI to PC Speaker due to sound tests done by the game to the hardware.

[Qbix]

what if you start the game with 3000
and then when it is running, increase the cycles (using ctrl-f12) to the desired value.

[Mohammed Sayed]

BTW, the problem is present in windowed mode.

I started the game with 3000 cycles. The problem was still there.
Then, I began to increase cycles by pressing ctrl-f12 several times.
When the cycles approached 10000, the game got fine.

My computer has:
Core i7,
nVidia 1060 GTX,
Windows 10 x64.

Please inform my whether there is a bug or not, and I hope you try to fix it quickly.
PS:
I had typed wrongly that the problem had been preset in windowed mode. The correct sentence is: The problem is also present (with N) in windowed mode.
